Dave
   Oh man, I can't believe it Dave.  The A5 continues to improve.  The sound staging and transparency have really opened up dramatically.  I'm continuing to hear better detail, including instruments I hadn't heard in the mix, and vocals I had misheard before.  The timbral nuances are more realistic, and the bass is really impressive.  I'm getting the word out to fellow Audiogon buddies about the quality of your work.  Btw, it was a fellow Reynaud Offrande lover, Russ Garrett "Leatherneck" on Audiogon who told me about you.  Thanks for the tip on the Isotek Enhancer CD.  I ordered mine today.

"To Upgrade -or- not to Upgrade, there is no Question"


"Own the very best!"


Stock high-end audio gear still leaves a lot to be desired.
Even ultra high end models simply fail to come close sonically to the same model which has been upgraded.
