[Sept. 27, 2018]
you Goldpoint! Transparent, precision, stepped-attenuation that
lasts through the rigors of a working mastering studio, day-in and
Here at Sage
Audio Mastering we’ve
been using Goldpoint for over 10 years - not once have their
attenuators let us down. Their precision, transparent operation,
and durability have been essential in the studio; specifically for
setting target analog Peak levels, and driving into equipment with
accurate control to achieve specific RMS and/or LUFS during
mastering. In addition, recalling session settings with their
stepped attenuation allows unparalleled accuracy.
The transparency and accuracy of Goldpoint attenuators have
givin us the
freedom to to create any desired tonality with the addition of detailed level
control for every record - keeping each recording true to the original
production, mix, and specific artist’s or producer’s vision.

| Goldpoint Stereo 24-Position Stepped Attenuator -
[May 24, 2017]
||I just wanted to say “Bravo!” and “Thank you" for the attenuator I got
last week. My long and frustrating search for a volume control,
which started about 8 months ago, has ended.
It started with a PEC stereo potentiometer,
reco’d in a diyaudio thread, which actually sounded quite nice but was
missing a bit of the top end for me. I then tried the ALPS Blue Beauty
but that one seemd a bit harsh and flat. So then I tried a DIY shunt
type stepped attenuator kit with PRP resistors and two naked resistors
for the signal. I really didn't hear that much difference between it
and the ALPS; neither was as good as the PEC.
I even built a DIY Arduino
based LDR controller since I also would like to have a remote control
for the volume. Once again, the sound just wasn't up to my expectations
although using the Apple remote, and being able to calibrate the LDRs
for different impedances/steps was interesting. Learned a lot though.
I happened on your product in one of the forums and it sounds just
right in my system. Now I can move on to something else!

SA1X - [October, 2014]
SA1X is stunning. I purchased based on a recommendation from my pro

I am running the passive attenuator directly from my source to gigantic
active speakers (ATC SCM150ASL.) The music is more immediate now,
and of course a source of noise has been removed, having switched from
a very expensive active preamp. Really the noise floor
has had an almost comical improvement. Superb."

Goldpoint V24 Stepped Attenuator Compared to "cheap knockoff" -
[May 12, 2013]
||"Thank you for
the fast shipment. Got the Mini-V installed in my KT-88 kit (Bob
Latino) based upon the Dynaco ST-70 chassis. Everything is
tight on this chassis and the Mini-V just barely fits in place of where
the old stereo-mono switch is located. The Mini-V replaces a low
end model stepped attenuator supplied with the kit that seems like it has
linear steps. I now have better low end volume
range plus additional steps which is fantastic. The Mini-V also sounds
better with less edge on the highs and tighter, well rounded bass.
Remarkable and a worthy upgrade indeed! Thank you again."

"Dear Madam or Sir,
a pair of Goldpoint attenuators for my Precision Fidelity C7 recently.
The line stage was anemic although the tube phono stage was sweet with
a pair of cheapo Bourns pots.
are simply outstanding. Every source I have put through the C7 sounds sweet.
Again the line stage seems to be the primary beneficiary but the phono
has benefited too.

investment, I would say they are worth their weight in gold.

Goldpoint Stepped Attenuators - [April
"Your attenuators come highly
recommended by more than one person I trust. This past week end I had the
opportunity to hear and feel one in a preamp that was custom built by a
NASA engineer in the home of one of my customers. The system was all custom
built with among the finest combination of vintage and modern parts money
can buy. I would estimate the system cost over $75K and it sounded better
than anything I've heard at any high end audio store or audio show.
They could have used ANY
attenuator on the market and told me they had a "collection" of hand built
stepped attenuators they were no longer using since you convinced them
to spend less than 25% as much on your Mini-V. The feel of your attenuator
was silky smooth. When the volume was changed it was dead silent. The sonic
signature was undetectable. What more could you ask for?
Unlike many companies I don't
consider a quality attenuator an "upgrade option." I would rather "cut
corners" with no fancy chassis or no fancy packaging then a critical part
in the signal path ; ). I certainly won't be your biggest customer, but
if I decide to use your attenuators in my products, they will be the ONLY
option I offer." B. Z. (Ontario

SA1 - [February, 2011]
I received my new SA1 Passive
Preamp this week and I am impressed! The workmanship is superb and the
sound, WOW! I had been using a dual 100k pot in a homemade case for
my master volume and had some problems with it recently. I decided it was
time for an upgrade to something much better. The SA-1 has given my system
a whole new clarity that is amazing, especially in the upper frequencies.
At first, I thought I was hearing what I wanted to hear, but no, it's for
real! Who would think that a 'Passive' unit could make such a difference?
I am a guitar player and I write, play and record my own compositions.
With the SA-1 in the playback signal chain, my recordings have come to
life like never before and that is a beautiful thing. Thank you Goldpoint
for a truly wonderful product! J. R. M. (Dedham, Massachusetts)

my Mini V attenuator, and have installed it in my Monarchy M24 DAC.
I had read success stories about this upgrade, but was completely unprepared
for the difference between your product and the stock Alps pot. It
literally transformed the preamp side of the DAC. I have an integrated
amp (Rogue Tempest II) with a passive preamp section which is very clear
and nice, and I was missing that clarity with the active pre in the Monarchy.
But with just this one change, the active pre is one of the nicest, most
neutral preamps I've heard in the sub $1,500 category, and to think that
is the result of a "volume knob" is truly eye opening.
This thing is DEAD quiet,
and you can hear WAAY into the recording venue. It isn't sterile
sounding, but just lets the signal through. Man, what a piece of

SA4 - [September, 2008]
||"I thought about
trying a passive “preamp” for a long time. I had a decent active preamp
already that I've been happy with for about 10 years. I knew I'd have to
spend between 3 and 4k to do better, or take my chances with a used eBay
unit. So after a fair bit of research, I decided to try the Goldpoint SA4.
I knew what the advantages of a properly designed and built active preamp
were and what disadvantages existed with passives. Well, after a couple
of weeks of listening, I have to say that I'm quite happy with my decision.
The SA4 makes it hard to believe I could do any better at all with an active
unit. Any disadvantages in gain, or dynamic headroom are far outweighed
by the crispness, clarity, focus and transparency all at a small fraction
of the cost. 24 positions are more than enough and the unit has a great
“feel”. I now have a greater appreciation for the rest of my gear. Excellent
product, I highly recommend. Sincerely, F. S., (Pickering,

New SMD V24 - [July, 2006]
"Got the unit in yesterday
and dropped it into the power amp...first listening impressions: Wow!
Talk about detail and clarity! I noticed it big time right away,
No hum or noise, and perfect tracking. All of a sudden my little
EL34 triode-wired amp fed by my old restored Fisher R200 fm tuner has highs!
EL34 is not exactly known for ultra 'high high' freq extension. The Goldpoint
has extended the top end of my amp to a level I never knew possible; easily
an extra 2-3k. I even had to reposition my speakers to adjust.
There is no glare or 'edge'ness in the top end, just a 'smooth sounding
extra extension, but certainly more high end than I've been used to. I'm
sure it will sound even better after it 'settles in' over the next 100
hrs. of listening too.
I'm now having to think
about upgrading my bookshelf speakers, which I never much thought about
before. Amazing that an attenuator could radically change your system
so much! I suppose this speaks as much about the system too, as I
certainly can hear about any change I put into it, that is, if there is
supposed to be a change, heh. Well, I'm very proud of my little system
now; and the Goldpoint is certainly the final crown!
||The level of
detail, very good before, is now just fantastic, and even at very low listening
levels. I think that the taper is about perfect. At the fully
attenuated position there is absolutely no signal whatsoever. At the first
step the signal appears, very low but noticeable, and usable, and increases
accordingly and perfectly in both channels all the way up... I'm impressed
...Amazing what I'm hearing
now, after listening to this amp in many, many different setups over the
last 7 yrs.
Well, the Goldpoint is the
best upgrade that's happened to it, since I first put in some 1958 Mullard
xf1 power tubes, and that's saying a lot! ...This thing was certainly
worth every penny! Ralph Harris (Bakersfield, California)
Mini-V Approval - [March, 2004]

Philippe VAIDIE, (senior sound mixer at France 3, National French TV)
24 Positions Are Indeed Enough - [November,
Before ordering I was initially
concerning about the number of steps in the attenuator not providing fine
enough adjustment. After it arrived on Thursday last week and quickly installed
into my Transcendent Sound Grounded Grid it proved unfounded with just
the right number of 'clicks'. First listening tests immediately showed
correction of channel balance at low levels (the main reason for investigating
upgrades to the original cheap plastic pot). Having the attenuator significantly
change the sound however was a real surprise! The sound was immediately
more detailed but with a slight over brightness. After letting the system
settle in over the next few days however the Mini-V has now found its way
with the music (particularly with chamber classical, small ensemble jazz
works and vocal pieces) and shows a level of detail, clarity and overall
tonal balance previously unheard through the already excellent Grounded
Grid. Thanks again for your assistance! A. B.

than my older unit. Depth? You bet! Dynamics? Absolutely!
Most of all it has great transparency. It is an outstanding product
at a very reasonable price." R. F. (Winnipeg, Canada)
Mini-H Compared to Alps Blue Pot - [January,
received the shunt type stepped attenuator on Friday. The instructions
were very clear and the quality of the parts were very high. It took me
about 2.5 hours to put the kit together; however, it took about another
3 hours to install it because I had to make new holes in the amp's metal
cabinet, without using a drill! However, in the end it worked beautifully.
I wish I had thrown out my Alps Blue volume control earlier and bought
this one. I now hear vast sonic improvements all across the spectrum. The
bass is deeper and better defined, the mid's and the highs are smoother
and better defined as well. Spatial clues and imaging have also greatly
improved. Tonal textures are more accurate, and there are details jumping
from my records that I never heard before. Overall, the new attenuator
is absolutely great. Now my HD83 headphone amp is really singing. I hope
you sell many more of your stepped attenuators.."

Goldpoint Ladder Attenuator Application
- [August, 2002]
"The attenuators arrived
this morning and i have fitted a pair to my own pre-amp, this has had many
other potentiometers tried in it and i can only say that were i am now
is were i would wish to have been a long time ago! All others altered the
bass or treble in an unnatural way, violins were more "hi-fi" now much
more natural, low level detail now so much more part of the music as a
whole with older (1960's) recordings showing previously unheard detail.
My cd player also sounds like much more money has been spent on it. (i
am a turntable nut but also own a cd player) . Perhaps the conventional
potentiometer somehow is overloaded by cd's typically high output (2-3v)?
Finally and this is a very big plus i now have excellent control over volume
and able to listen at much lower levels also." --A.

Ladder Attenuator Assembly and Use - [June,
"Just a quick note to let
you know how I got on with the ladder attenuator. Assembly took me about
3 hours in total over a few weeknights - I took it slowly and was careful
with the soldering. It works beautifully - no clicks or pops at all, so
no need for the big ground resistor. I'm using it in my DIY preamp
which is a scratch-built version of Bruce Rozenblit's "Grounded Grid" preamp.
As for the sound - superb! A real improvement on the previous volume
control, and I couldn't be happier. I had a DACT stepped attenuator
before, and although it works well I had the distinct feeling that it had
a "cold" and "brittle" sound with a recessed midrange. I know subjective
terms like that aren't very helpful, but that was my impression.
The Goldpoint is much nicer to listen to, and I can't imagine wanting to
change to anything else." Tony (TG)
SA-1 / SA-3 Comparison Review - [June,
"When I received the SA-1R
(with Roderstein resistors) and the SA-3, my first listen was to
the SA-1, which I compared to my reference Monolithic PA-1 passive/active
line stage. Although I did not use an SPL meter for level matching, I was
very familiar with the source material and I could easily hear improvements
in resolution, clarity, bass definition, and image specificity. Although
the Monolithic is a little more flexible with a tape loop and a second
set of outputs, and was a definite improvement over the Creek OHB12 passive
linestage I had previously tried, it was not in the same sonic league as
the SA-1R. The only reservation I had concerning the SA-1 was that voices,
especially female vocals, had a slight glare, or edge on high pitch notes.
I use silver interconnects and speaker cables throughout the system, and
I suspected that I hadn't heard the glare previously but that it was inherent
in the silver cabling. It took the increase in resolution that the SA-1
was imparting to expose what I assumed was a cabling flaw. As it turned
out, when I substituted the SA-3 for the SA-1, all traces of glare disappeared.
Additionally, I detected improvements in channel separation, the outcome
of which was a perceived widening of the soundstage. All the improvements
that were present with the SA-1 were there with the SA-3, in spades!
I am hearing details in my musical selections that were barely audible
before, and even some background sounds and voices that I never detected
before! The SA-3 really helps to bring performances closer to the listener
and you really get a clearer sense of the emotional intent of the performer(s).
The other day, I tried to stop listening to the equipment so intently and
just get immersed in the sound, but I found the ability of the SA-3
to unravel hidden musical nuances so engaging, I couldn't resist
being drawn further into the listening experience. Thanks for a superior

Mini-Vs Used for Active Load Line Settings
am using an active load line in the cathode follower stage of the driver
of my Atma-Sphere M60 amp. This circuit performs really well with the proviso
that the resistors in the active load line are balanced and tuned. This
usually requires a precision potentiometer, but I didn't want to send my
signal through such a noisy device. Arn and I designed a set of resistor
values [over the phone] that worked with the Goldpo- int rotary switch
such that I basically had 1% detents over the range of resistance in question.
When I finished building the amps, it was really easy to balance the load
lines and they sound absolutely incredible."- --Alok
