What Some Of
Our Customers Are Saying:
.........After
playing this new unit with all my original gear I was stunned. The mids
(especially voice ) grabbed me in the gut. Sometimes, when I play Miles
Davis( the bitches brew ) I'm stunned with how awe inspiring the instruments
are. If you are thinking about tubes I'd start talking to Bill and let
him lead u out of the wilderness.

Bob Smith
of SP Technology Loudspeakers wrote
this, after listening to our Reference Jolida 801 with V-Caps at a recent
Chicago Audio Society demo:
..........."Also, we absolutely must thank Bill Baker of Response Audio
for building the incredible sounding Jolida 801's that were used. I guess
its about time I shut up about tube amps 'cause I didn't know what I was
talking about in the past. Those babies were incredible! They didn't have
the mushy low end or edgy highs I've heard from tube amps in the past.
Although I will make one point in my own defense. I've always said that
there was no reason that tubes COULDN'T sound as good as S-S, just that few
manufacturers ever make them. Well...Bill's one that DOES! That thing was
one of the best amps I've ever heard - PERIOD." <

Shown
below is my personal Reference 801 amp with Translucent Emerald Green face
and tranny cover top plates. Custom laser engraving has not yet been done on
this piece. Other features in this amp include remote volume control and a
main-in feature to be used with an outboard preamp. Now running Valve Art
KT88 tubes with over 1200 hours of use.
The overall
presentation will give you a sense of realism never experienced in the past.
Use of only the
best available components is standard practice in the Reference RA-801A. To
guarantee unsurpassed performance, we use Reference Grade Teflon
capacitors, Riken Ohm carbon resistors at the grid locations, Dale/Vishay 1
watt, 1% Metal Film resistors throughout the signal path, high purity 24 awg
Silver wire for signal inputs, Fairchild "Ultra Fast-Soft
Recovery" diodes, upgraded power supply filter capacitors, Electro
Harmonix 6550 power output tubes and much more!!. Please remember each
amplifier is custom built and they take time to manufacture, but I assure
you they are well worth the wait. Built to provide a lifetime of musical
bliss, the Reference RA-801A is probably the best sounding integrated
amp on the market today. At any price.
Due to increased sales of Signature and Reference products, all amplifiers
are built to order.
Reserve yours today. Call for turnaround times.
