What about 845 tubes on Wilson Sophia 3...?

I assume that I also think not all 845 are equal, thats matter of design and equipment structure that defines the sound criteria...but I really dont understand what the distortion makes good sound could anybody clear this subject...if we audiophiles like the distortion (as some describe as to be) how you gonna define the good sound as a bunch of distortion...man I am getting confused here..maybe this is gonna take another threat subject..very interesting and confusing matter.

Nagra was the PP 845 I had in mind....Melody also makes them. Im not a fan of Cary 805s and frankly, they measure terrible for SET.

I don't know about Melody's P-SETs, but I can say the Melody M845 SET which I own is quite nice. If the bigger ones retain the magic at higher power, they are definitely worthy of consideration.

Nagra is one of my considerations..thank you for your very valuable feedbacks, before trying is not possible to comment but anyhow i am digging to find a gold. another consideration a conrad johnson lp275 but is gonna cost me a fortune anyway if you have also experience on conrad johnson running with wilsons are quite valuable thank you again and happy listenings to all

For whom is interested..I added Quad II mono blocks (15 watts on KT66), very good match with sophias. My respect for my speakers are improved they are singing like birds, off course vintage Quads are a big part of this contribution..They did miracles 40 years ago, very surprising to hear that they run side by side with krell on 600 watts class A..I love this hobby..
