Upgrade any stereo amplifier to an integrated amp for just $1500.  We add three single ended (RCA) inputs and a remote volume control.  

300B Amps have a
reputation for deliver spectacular midrange.  There is a musicality and charm that can’t be matched by any other
tube.  They are dead neutral in the
midrange and offer spectacular clarity and detail.

The downside of a
300B amp is that they tend to have rolled off treble and flabby bass.  Major adjustments have been made to this
edition of the venerable Diavolo to address these concerns.   

The NEW Diavolo 300B
Copper Reference has been fitted with our MK2 Standard Power Supplies and Transformers.  These massive units ensure complete control
over your speaker’s drivers and deliver much tighter and more refined bass than
you thought possible from a 300B.  Additionally,
the transformers were explicitly designed to retain high frequency output.

We didn’t stop
there.  By upgrading the Diavolo to our
Copper Reference standards, capacitors and resistors were selected along with
continuous cast copper wire that ensures high resolution in the mid ranges
while enhancing the frequency extremes.

This makes the
Diavolo 300B Copper Reference a very special amp.  With virtually silent transformers and a
miniscule .4mv of noise per speaker (.8mv total), the Diavolo 300B Copper
Reference is the perfect choice for your high efficiency speakers. 

Best results found
