One thing I've noticed in this thread, "The system" revolves around the Preamp. Others seem to center on power amps. Then there are people who build from the speaker, BACK.
Then those that have learned that ALL the speakers, amps, preamps, and cabling are just 30-40% of the sound. The room, the Power supply, the placement, matching components, vibration control, Source, EVERYTHING else, but gear should be considered.
I'm sure you've got a handle on good VAC, cabling and like. I'm not here to say one brand is better than the other, but I will say, I like tone control in my preamps, I like Lpads in my speakers. Those TWO thing are really controversial. HE speakers with lpad can be tuned and toned down. Same with Preamps, small differences in SOURCE, sometimes a tonal change, (not TOTAL).. make for a much easier fix, than gear change or just can't listen to it.
One of my systems still uses 78 mono stuff from time to time, its old I mean REAL old...Those preamps are point to point. I wouldn't use that system with several sources hooked up... Crosstalk.. You won't like it, if you haven't dealt with it before.
If you're looking for pieces of art, there are some truly fantastic pieces out there. If your looking at tube sound with a practical application, in mind. PtoP can be tough and expensive to get right. IMHO though ptop is the bomb, Vinyl a great valve set up... you'll be playing hooky from work for sure..
I like ALL the different stuff, A great Valve preamp and a pair of great SS amps, just crazy good..No names but Class Ds are a great combo for me.
Enjoy, 51 years a ValveHead... Just wonderful..
