CUSTOMER TESTIMONIALSI can recommend him whole heartedly and feel sure that despite the cost involved even vintage gear such as the preamp I described can sound absolutely fantastic and represents great value for money. For many cash strapped audiophiles( such as me!) I think this is the way to go! Musical Fidelity The Preamp Stage 2 Upgrade – Bob Leslie
Hi Lee,
Just to let you know that the repairs to the Marantz CD94 are working fine and the Quintessence +5v Regulator upgrade has made an amazing difference. There is much more detail and it is far more open now. It seems to have brought out the best in the various previous “upgrades” you have done for me 🙂
First chance I get I will let you have my Amplifier to go through as you suggested…!
All the very best
Steve

Hi Lee, I must say, the amplifier sounds really lush, the knobs work without distortion, the sound is to die for! The bass has improved as well as the mids and highs. My system now plays music! Wow! I can’t wait to her what it sounds like after I get to the 300 hour mark!Lee, I can’t thank you enough! Thank you very much for this! With Kind regards, James
