Hello Lloyd
Yes the repairs turned into a bit of a saga. It came back not sounding right, an absence of bass slam was the issue, and then it failed again in the same way as before, so back it went.
Finally got it back last week and it's an absolute revelation, to the extent that i am taking it off sale.
Or to be more accurate, increasing the asking price to reflect what i would actually accept, so two thirds the price of a new 2160 ?
I have to concur with you, ime valve pre amp - transistor power amp is the way to go, although I've yet to hear any hybrids (Tenor springs to mind)
My instinct now is to keep my 2060 and supplement it with another exceptional power amp(s), say Wavac 833's.
What i am hearing is so hard to describe, and the normal hifi terms fail me. For back up i used a pair of digital monoblocks, that initially i was very impressed with; there seemed to be no drop off in perceived sound quality, although i did find them a little fatiguing in extended use. But replaced with the 2060 suddenly the magic was back, my system went from whizz bang impressive but lacking something, to a sound that draws you in and keeps you there
As we unloaded the 2060 i had a cheap supermarket dance compilation cd playing simply to warm things up, which i left on with the 2060 now in stream. My goodness, i couldn't believe how good it sounded, so good i was tranfixed and listened to it all the way through. I went from hearing a collection of noises perfectly reproduced, to experiencing a musical event that was impossible to interrupt. And so it went on, anyrhing thst i played, maybe only intending to listen to ome or two tracks, got played right to the end. There was so much texture, depth, impact, slam and atmosphere.
And when i swapped to my recently acquired AF 301 i was literally gobsmacked. The familiar music now just had so much more body and drive
So now my daily routine is transformed. I used to come in from walking the dogs, listen for a bit then lose interest and do something else. Now i am rooted to my chair, each disc inspiring the next, hours passing, late to bed. I am certain that this iteration of my system has never sounded so good, the only hesitation in saying it's the best sound I've ever experienced comes from the memory of how certain bits of certain tracks sounded via dipoles. But that system was also capable of sounding nasty and thin with less than perfect material, wheteas this was absolutely on the side of the artist, getting to the heart of what they were trying to achieve, drawing you in and keeping you there
Btw Lloyd, did you see my post regarding subwoofer installation?
I ask because iirc you said that you only ran yours barely on, setting >5, which was how mine were when set up according to Velodynes's method.
I achieved big improvements by moving it to what the automatic installation system decreed was a sub optimal location, but where it had to work a bit harder but complemented the speakers far better and dominated the room far less
