I have gone thru various iterations using different systems, simultaneously but none lavish and none really expensive I generally have 3 systems function ready to play at present the main rig's power amp is tube.
I would like to comment that a tube preamp or a tube in the window of a an integrated SS power amp. Does not yeild a tube sound. I struggled for 6 years to find the synergy Sanhar is evidentily speaking of. The same thing happened to me. I always liked tubes but thought that I liked power even moreso.
This led to constantly using an SS power amp by many manufacturers of different ages etc. only to hear the same flaws in my system and it was at times brutal.
I also had a 40 watt integrated all tube for the WAF system. I prerred it at times to my big rig . The problem was it never quite managed to power the dedicated lisiening and audio equipment storage room even though my speakers were and are ( all 10+ pairs) fairly high sensitivity. So I used at least 100 watt amps which in a tube amp can be stratopherically priced. I added a tube pre an ARC believing that would be all that was needed. It was an older but well respected unit confirming an old friend's thoughts. The change was slight and not the key element.
Finally I had an opportunity to buy new tube Monoblocks rated at 78 wpc Opera/Consonce Cyber series 800s with 4 6CA7s a side and the requisite tonnage in the trannies. That changed the sound completely. Every time I listen to its off to Nirvana.
I do have the fix with what isn't broken gene habit, albeit not as fully expressed as TVAD and after 8 Mo. I have changed the system replacing the older ARC with a smaller inexpensive used AE-3 pre with all of 2 6SN7s but I have many to spare and the best by reputation.
Now that did it I have been utterly satisfied, to my own amazement thinking I would never find the answer. BTW it was a banner year the WAF system with the 40 watt integrated is now graced with a Jadis DA-60 using Gold lion reissue KT-88s (X 8 talk about spending.) Any way I have to get some of the accumulated amps up for sale.
