Hi Lee,
I was in a similar situation to you recently and ended up with an Acuuphase e-450.
I am really happy with mine, and also use the optional phono card for LP duties.
Having heard some older Accuphase amps I was surprised to find the newer models sound a bit more open and detailed.
While i havent heard the Diablo, most reviews describe it as being a very detailed fast sounding amp so my guess would be it could sound somewhat bright in some systems?
If you have any other questions about the E-450 feel free to ask.
Regards Rob
