@freediver -I’m not a loud listener on this rig, so what you say makes sense. That’s reserved for the bigger one in the livingroom, which BTW, has ProAc D30R floorstanders. I used a soundmeter and typically listen at 60-65 db. I "cranked-it up" and in this room 75db is plenty loud.
WRT tubes and cables-I started with the stock tubes, Tung-Sol EL34 and TungSol 12AU7, which are really good. After the requisite amp burn-in period I moved on to NOS Brimar 12AU7, mid 1970s, blackbase EL34/6CA7 Siemens. I’m using Quicksilver silver RCA interconnects, which IMO are a STEAL.
I appreciate your input!
