Thank you for those ulta-quick responses. Yes, i understand Primaluna’s design philosophy of auto-biasing, operating at the lower end of the tubes operating power range, and ease of rolling. Those were included in my original trade studies that led to my purchasing it. Maybe Im a little sensitive to tube life as i have a Primaluna CD player that is challenging me to isolate where a transient crackle and fade periodically appear on one channel. Its aggravating and i just need to troubleshoot and isolate it to hopefully just a failing tube. To your point millercarbon, it only has 6 tubes whereas the Dialogue HP has 14. I love and am “musically fulfilled“ with the music my current system presents. My next step (because i have the same bug everyone in Agon is aflicted with) will be upgrading speakers from the current Triton III’s to most likely either the T-Refs, or T-Ref.One’s because i love the Goldenear sound of their lower in the line-up speakers and the fact that the Primaluna only has to drive the mid’s and hi’s putting even less stress on the amp (rarely seeing 11:00)We all have a great hobby/obsession that many (including everyone else in my extended family) don't understand. Luckily, in my case, they understand that it makes their husband, father, grandfather very happy. And that’s not a bad thing!
