Tube Integrated Amps

I have been happy with the Sophia Electric EL45. Economical (+/- $600) used, and sweet sounding for Vocals, Jazz and acoustic. Puts out about 40 watts, push/pull. The one annoying fact is they label all of their amps SET which stand for Sophia Electric Technology. Has nothing to do with Single Ended Triode. It is a great starter amp, and has suited me well until I can find a modded Shanling to match my Shanling SACD.

Check out the LS-960I from Aronovaudio.com for self-biasing, carefree excellence in sound reproduction, including the low end control and slam usually associated with solid state designs.
The era when it was a requirement to have preamp and amp separate components is past. You are correct that some of the best sound today is available with the integrateds.

Very satisfied with my Consonance Cyber 10 Signature, 2A3 tubes, 12 watts a channel....inexpensive to boot!

I am using a Jolida 502A tube integrated amp. I have been extremely happy with it. It's rated at 60 watts per channel but performs way beyond that with my Chapman speakers and their 4 ohm load.
I have upgraded the line stage tubes once and the power cord twice and now the amp is going to Bill Baker at Response Audio in New York for his Reference Modification upgrade. I think with the reputation of the Jolida amps, especially the ones that have been modified, they certainly have to be on the list of tube integrated amps...especially for those looking for bang for the buck components.
