Curious about how you would drive speakers with the RWA Isabella?
It has a headphone out, so that fine. Its just a pre-amplifier though, and need a power amplifier (like the RWA Signature 30.2) to drive speakers.
Never heard it. But given how pleased I am with the Isabellina and 30.2 I am sure its really nice.
You wouldn't be able to drive speakers with the RWA Isabella, nor with the WA2 running as pre-amp, either. The criterion for this thread was to double as a part of any amplification component, either as power amp or pre-amp, or as an integrated amp.
Yeah, the Isabella is the one I really want to hear for myself!

Also note: you can find preamps and integrateds that have a line out or tape out. You then can connect a separate headphone amp to that line/tape out. If you buy used and have the available real estate in your home, that combination can be a much cheaper route than paying retail for a "one box" solution.
That is a very astute observation. Thank you very much. It has made me reconsider the sale of my Bel Canto PRe1 which has two different kinds of pass through and will be just right for adding a dedicated headphone amp which does not have to do double duty as a speaker amp. Now, I can really look at finding a used RSA Raptor or Woo Audio headphone amp, which would not use up all of my budget.
The Cary SLI 80 is an integrated. You have it listed as a Pre-amp. It is 80W Ultralinear Pentode PP or 40W Class A triode PP with the flip of a switch, which also is active (pentode/triode) through the headphones. The Cary SLP-05 is a Pre amp with reported very nice headphone out. It is a beautiful pre-amp. I love the SLI 80 in its standard Cary setup with my Grado 325i and Grado 60 'phones. The 325i sound much like my Focal Chorus 716 speakers do but with more detail with that amp. I am biased about it..........
Thanks for putting the list together, it's interesting.
