Hi Geoff,
Here's my present setup...
Main system:
Sony TA-E86B preamp, heavily modded - sounded good before the mods; sounds wonderful after modding; great clarity and dynamics.
Belles OCM-200 power amp - terrific sounding amp, very natural, open, slightly warm.
Second system:
Sugden C28 and P28 pre/power amp pair - less detailed than the main system pair, but lovely fluid, dynamic, rich sound. Wonderful combo!
Wish list includes an Onkyo Integra P308/M504 pre/power combo that I heard at someone's house - amazing clarity and effortless dynamics...quite startling really, I had no idea Japanese gear could sound so good (ingrained bias at work here).
And one of these days I'd like to try tube amps
Best,
Svend
