Sophia Electric 91-01 and 91-5 300B

Hi,
I have been using a Tannoy Turnberry SE speakers for the last 1 year, I was driving it with Naim amplification and was happy with it. However I would like to add a good tube amp to drive the Tannoys. I have been listening to various amps. It is quite evident that SET based on directly heated triodes have a special magic about their presentation. However most DHT SETs are low powered, within 10 watts. Recently I read some very good things about Sophia Electric 300B amps, especially driving Tannoys. Jeff Day has given glowing review to it even replacing is reliable Leben 660P. But before I pull the trigger I am looking for some first hand comments from the community here which is expectedly more devoid of the reviewer's bias. Has anyone heard it ?

Moreover I am also looking for some views on the various models that Sophia offers, 91-01, 91-05 etc. Is it really worth going for their more expensive models like the 91-05 when the 91-01 already seems to be doing so well ? Has anyone heard the higher models ?

Dilly, thanks for that input. Which preamp are you using with the Sophia amps ? Did you consider their higher models, 91-03 and 91-05 ?

Charles1dad, thanks. Jeff's review was a high motivator for me to try the amps. I just could not pass over knowing Jeff is a big Tannoy fan & raving about a 300B amp on the WMR! He also values musicality very high which is my top most consideration as well. So far the amps are breaking in very well - Sue mentioned that I should have at least 100 hrs in them to hear the full potential. In my experience anything with transformers take over 300 hrs to put out the last bit. Long wait & I can't wait to hear them fully run in.

Pani, I am using a Supratek Chardonnay as my pre. I did inquire about the higher Sophia models but I believe there are significant price differences. If I remember correct 91-05 will be around 20K. Given the difference is 3/4 more my view would be to try the basic first & you can always upgrade later if this is the route you decide.

Dilly,
I agree concerning components with transformers, especially amplifiers, they need ample time to burn in. I'm certain your Sophia will continue to improve as the hours accumulate. It will really begin to sing.

I have had several Sophia's with a range of speakers -- most recently Avantgarde Trios. They sound good, solid middle of the pack on their best day. The parts are cheap; the units are not well-constructed; their tubes are low quality but sound great when they work.

You should read the separate recent thread on Sophia quality. Even Jeff Day's article makes a passong comment about his order from Sophia being incomplete.

I advise you to go elsewhere.
