Clio09-
You might ask Paul about your Cary V12i and see what he thinks. CAry makes very fine audio gear, but as I am finding out, even very good units can be improved.
You probably recall Sam Tellig going gaga over the MF A300 when it came out and it is still snapped up on the used market as an in demand piece of gear.
Well, it is a much better integrated amp now.
As you know-TRL made its' reputation for the last several years doing SOTA tube amps and preamps costing major bucks.
I think they have a year waiting list on these big buck units.
I was kind of like you-wondering if I should buy a different preamp/amp or integrated or see what TRL can do?
This has turned out to be every bit as much of a positive change as one gets with a major component upgrade.
The noise floor element still sort of amazes me as it was so apparent right when I turned it on after getting it back.
If anything, they could maybe evaluate it to tell you if they thought it would be worth it.
