Hello from Spain,

I have a Cary Audio integrated SLI 80 signature from 2004. I have used two 6922 JAN NOS USA (excellent and balanced tube) and now I have Amperex NOS Philips E88CC in preamplifier section (another sonic and different texture...liquid and defined mids, more tridimiensional sound stage and extended highs, but less bass…), with two 6sn7 wgta USA and two RCA 5u4gb in rectification sections. Recently I made an order of two Sophia Electric Princess 274B rigid plate and two Sophia Electric 6SN7 tubes and the change was....simply wonderfullllllllllll!!! The general stage grows more and more in all directions....the roundness, smoothness, 3d, extended bass in the music texture is really amazing!!! There is not any sign of harshness anyway... Every note sounds like pure silk.

My congratulations by your great work and I cheer you up to continue in that way.
