Phono stages are very special to me. I have a large record collection and never made the switch to digital. I had a field day when everyone was selling their record to Goodwill. $1 each. I fear these good old days are over as others are discovering the magic of vinyl. I have been building phono amps for many years and have tried many and built many others. My favorite is to use tubes for the amplification. The main downfall of this approach is that tubes can be noisy. Phono amps multiply the signal many times over. Much more than other types of amps. Noise is multiplied as well. So what is the solution? I have found that there are a few ways of making an all tube phono stage quiet.
I started with a commercially available board. I used a combination of Wima capacitors, 1% film resistors. All traces on the board are made of Silver for detail and power. All parts are hand selected to insure a large soundstage. Transformer is a custom made shielded Torrid, which can run on 120/230/240 volts. It has that you are there quality. As you can see I have changed to a new board and custom, hand made power supply which maximizes the design. It is more quiet and with more bass than ever. The Etude Amplifer is equal to amps that cost much more.
HOW CAN THIS AMP BE ANY GOOD AT THIS LOW PRICE? I have used commercially available boards of a proven design to keep cost down. I have used a standard chassis instead of paying hundreds for a custom job with printing. This allows me to buy superior parts and still keep cost down. You will not find this unit anywhere else. It may be the best deal in the audio business.

I am leaving in the morning on vacation and won/t get to listen much until I get back. From what I have listened so far, all I can say is awesome, awesome, awesome. I will just rotate my Moving coil cartridges. I have some older preamps for MM. Other cartridge I have is Low output moving coil Grado Sonata. Haven/t tried it yet. Thanks for everything. Don/t know what brand of tubes are in it, but they sound excellent to me. David. Here is another one. Hi Tom I changed the setting back to M C @ 100 ohms after trying a higher setting,I took the sot out of the configuration, I warmed the amp up with one side of Bach and then I played my reference album, Dark side of the moon. HOLY MOTHER OF GOD this would equal the most discerning systems at any cost, the separation and darkness of the sound stage just blew my mind I am not changing the cartridge, it could use a little more mv output to be perfect but it is not worth the effort as this turntable is a bear to change. Thank you for leading me away from the H O M C, I did buy the denon 103 r and I am going to install that on a Thorens 160 that is being refurbished and up graded with todays technology or possibly a VPI classic if I can get the right price on that and sneak it into the house so my wife doesn't see it. At any rate I could not be happier with this very fine pre amp you would be hard pressed to find one that functions as flawless at any price. It is a great product and you are a absolute pleasure to deal with. I will send you the tracking # when I go to the post office, but now It is Beatles time Thanks
Here is another review just received: Douglas Robert Hounsell Fri, Oct 17, 2014 at 2:25 PMTo: Tom Kenny Good afternoon Tom,The preamp is here and I must say I am quite impressed with the build quality and construction of piece. First rate and it looks great in the rack. However looks aside after plumbing it up into system the real proof of your Phono pre with the balanced outs is what really matters to me! After listening to a MFSL Rolling Stones “Let it Bleed” I was quite pleased, then on to Stealy Dans “Aja” I was rapidly becoming an Aural Thrills Audio fan big time. The punch combined with a subtle smoothness is magnificent. Lower register notes on piano are outrageous clean, tight and dominate. I am fully aware how difficult it can be to accomplish this as I worked my tail off with Leon Russell’s engineer one evening getting this very thing “right” at a show I produced and engineered some years ago. Thank you for your devotion to what matters in your craft. Perfection takes its toil on the less passionate but their always will be folks like me that understand and appreciate folks like you. Now on to the Beach Boys “Pet Sounds”Thanks AgainDoug Hounsell[Quoted text hidden] Hi Tom, Yes I received the pre amp in good condition and I sent you a response on Ebay for your product.
I set it up and it sounds great! I've invested in an affordable LP vinyl washing system, and with a modified vac system, my record collection has been given new life!
The Marantz SR8001 amp and Technics SP15 turntable/Grado cartridge are sounding really clean with your phono stage.
Thank you for your excellent workmanship.
Received the amp and plugged it in to the CD input of my Yamaha A-S700 amp. I have a Yaquin MC-100B that’s been modified by a tech in Australia and a pair of Sonus Faber Concertinos, but all unfortunately still in storage. I am listening to some Australian country music, the hairs on the back of my neck are standing up - I’ve honestly never heard it sound so clear, present and detailed. Can’t wait to spend some quality time with your preamp. Maybe I’ll just plug the headphones in and kick back for a couple hours…. Thanking you, sir.
