Reviews

Below are just a few of the many positive reviews and comments that have been posted on forums or emailed to me directly.

“I received the amplifier early this afternoon and, after a warm-up period, have been listening with pleasure until now.  It is on the way to becoming my favorite amplifier.  I am particularly pleased about how the instruments are distinct from each other and correctly positioned. I’m happy with the silver color and delighted with the performance of the amplifier. I was a bit surprised that I could hear the difference between the Spud and the amp I had been using so easily. I particularly noticed that Spud delivered more detail. I’m enjoying replaying my favorite CDs and hearing them how good they can sound! Thanks again for the extra effort and time you put into this project.”

“I placed a class A/B sand amp in the system, and while it was dead quiet at any setting of the volume control, the musicality was severely lacking compared to the Spud. What was most amazing to me was that the 50 watt per channel sand amp produced only a fraction of the bass that the “little” Spud amp produced.

I’m not sure if it is due to the single gain stage or something else, but the Spud is easily one of the most musical and involving amplifiers that I have ever heard ….. at any price. It is coherent beyond belief.  The Betsy 8″ full range drivers in my basic speakers are only 92.5 DB efficient, but having no crossover components they play plenty loud with the Spud in my 16′ x 26′ room.  I seriously think that if more people could hear what I’m hearing right now you would not be able to keep the Spud in stock.”

“I have quite a few amps, mostly Decware,and one Bottlehead Stereomour 45 using the 45 tube which is the closet I’ve found in sound to the Spud amp, pound for pound the Spud rules. I’ve done some tube rolling and found the Tung Sols my favorite, very open in my 9×13 room, don’t listen very loud, but turned the volume to 11 o clock today. Stunning!

I can tell you, maybe I’m hearing Mr. Brubeck as good as he gets, stunning!!!. Another, ‘have to go through my collection of CD’s again’ days. This amp has already embarrassed some other amps I own, all in the 2 to 6 watt range……..just so you know! 

Man this amp is so easy to listen to. Vocals may be the best I’ve heard. I listen to Joni Mitchell, Patti Barber, and Stevie Wonder, just so open and understandable., very happy with this amp.”

“The SPUD sounds wonderful. The layout looks so much cleaner and the new tubes sound very sweet. I just added some BCS to my Dayton Audio ps220-8, and the combination with the Spud is really sounding great. In this day and age to find someone who can do quality work with tube amps and be a true professional is rare and awesome! Thanks again Jerry.”

“Hey Jerry, Put my Spud Amp together yesterday afternoon. WOW! What a marvelous little amp.  The instructions and photos were excellent. The construction sequence was right on. Took a little over four hours to put together, checked my circuit and connections three times, then… holding my breath and crossing my fingers… flipped the power switch and was greeted with sweet, wonderful music!  🙂  My amp is dead black silent with the volume turned all the way up.
Thank you again for making this wonderful amp kit available. It’s really sweet!!”

“Dear Jerry,  I today finally got to unpack the Spud and plug it in. What wonderful care you took with the packaging. It was first rate – very professional. And the wonderful selection of tubes – Amperex long plates – how lovely.  I popped those in straight away – it was the green & yellow packaging calling to me… So far I have been happily listening for several hours, and with each hour the Spud is warming to its task and sounding every sweeter.

Externally it is much improved over the one Ricky built me. Very professional indeed. Fit and finish is first rate.  Sound wise – well I am sure that there is a “better” 2-3 wpc flea watt SE amp out there, but I am so very content with the Spud you built for me I certainly don’t feel any need to find out. Bass is much improved over the original, mids are glorious and the tone and timbre is very, very sweet indeed.

This is a seriously good little amp.”


James — Scotland

“Jerry, This is without a doubt the best value amplifier I have ever owned. I cannot compliment it highly enough. And this is before I’ve heard it paired with suitable speakers! I have a few pairs of speakers that could be magical with this amp: Loth-X BS1 (94dB), Tannoy Little Red Monitor (92-94dB-ish) & Fostex FE207E with Eminence Alpha 15A open baffles. All of these are far better suited (on paper) and should let the little spud shine.”


Dan — California

“Going from the Accurian to the spud was a nice improvement. There is nothing harsh about this amp and the detail is a sizable step up. My favorite part about it is the low noise. I always had some hum issues in this system, more so with the Accurian, but now there is none. My Denon tape deck always had a pronounced hum, but it’s all gone! I didn’t expect that from an amplifier change, but it’s true. Even though this is just a couple watt amp, it still has bass.”


Darrel—Michigan

“One of the noteworthy things about this particular record is the quality of the vocal recordings. Steely Dan is known for their ultra clean voicing . On Aja they are tight and their musicianship clearly shows.

The spud amp handled everything with ease. Tempo , punctuation and the blend of horns , voices, guitars move in tight coordination.  I immediately felt like the Spud amp presented this material in a cleaner and more open manner than my own amp could? This was immediate and came as a bit of a surprise to us.  This amp can do dynamics but it can also do subtleties equally well. Small inflections in the way words are used to paint pictures in my mind, Becker and Fagen had definitely found their groove by the time Aja was released and I spent an evening revisiting this LP on the Spud….I loved it back in 77 and amazingly still do today.

You have done a great Job here Jerry… Well done. I was initially concerned that I would have a hard time really recommending this amp. I mean, how good could it possibly be for so little money?

I am very happy to fully recommend this to anyone willing to give it a go. I will vote with my wallet, and I don’t pry that thing open for just any piece of audio gear. I am not in big hurry to return this and already think of it as mine. That’s a good sign.”

“The Spud has no hum, no clicks, and no pops. It is unassuming, quiet, and very easy to listen to. You hear what there is to hear, no more no less. It will not blow the windows out of your house, but it will drive many speakers to a very reasonable listening level.

I have done nothing but listen to music in my free time. I am like a little kid in the candy store. The Mrs. insists I am spending too much time in the dungeon. (of course there is Guinness in the dungeon) I have rediscovered a lot of old friends and am hearing them unveiled for the first time. I am truly amazed at what I’ve been missing.
I dug out the old Adcom amp and hooked it up. It will play louder, but it has no where near the sound stage or clarity of the Spud. That is the Spud’s strong suite. It recreates a musical experience that you can believe. With the lights turned down low the tubes have a glow that is almost seductive.

Thanks Jerry for reminding me how wonderful stereo can be.”
