Yes. Tannoy Canterbury GR with VAC Master 300iQ monos and matching Master preamp. The Master amps effected a vast performance increase over other amps. Nothing I’ve ever heard has made so much difference as those amps. The system now matches or exceeds the best sound I ever imagined for that room. I can still play with various phono stages & cartridges for "flavor" changes, and each change is rendered in its best light possible by this downstream.
My "sandbox" for experimenting with more gear combinations has now moved to a smaller office system.
I don’t have a "go to" artist for testing system changes because it becomes boring very quickly! I just use mostly ordinary LPs that have been in recent rotation (no digital at all! lol). Certainly not "audiophile" releases (which I find horrendously boring)! I suppose I do end up using Blue Oyster Cult, Magnum, and Quarterflash more than average. Also like a lot of 80s / new wave / synth wave and some heavy metal (including hair metal). There is a vast difference between a "good" sounding LP and a bad one, and of course I avoid the latter. But the good are certainly not limited to slow, sleepy female singers (like the usual suspects at audio shows).
