I own an all Fet/Valve system w/ an omega IV dac, biro speakers, parasound cd transport, and a fanfare tuner. I like it and can't think of anything better for the money. Seriously, if my income ever affords me to spend close to five-figures for each component, I'll go out and do some serious auditioning and, obviously, use what I have now as reference point. I'm not saying they are the best period, I have heard of several people who opted for other brands for various reason. But overall I am content with the performance, something that seems quite rare these days with audiophiles, and have no plans to upgrade, aside from better acoustic treatment and eventually the matching sub.
