I have a special version of the Stealth monoblocks. Dr. Lloyd used to offer this for a while
but discontinued it. It is the same design but uses tube rectification and allows for use of
6 volts or 12 volts input and driver tubes.
I use them with my Octal 6a SE preamp which has been replaced by the Magic 5B.
This is a combo made in heaven, the sound reminds me of the famous QUAD II amplifier
but with slightly more definition to the soundstage. The highs and midrange is among the
best I've heard, shimmering and smoother than velvet, the low end does'nt have much
oomph and the power is on the low side, you need speakers with over 90db efficiency
to realize its full potential, never-the-less I'm using these with my 88db speakers and I
get satisfying output.
If you have medium to high efficiency speakers you would'nt go wrong with the monoblocks.
Sorry for the delayed response, just checked the forum.
