Tube Guru 6C33C Amp- Has anyone heard this amp??

We at Beauty Of Sound import TubeGuru into North America. Our showroom is just outside of Albany, NY and is available on an appointment basis for demonstrations. The current reference system is comprised of TubeGuru TubeMann phono stage, TubeGuru PSE GM70 monoblocks, Leonardo Planar Magnetic Ribbon speakers, Tourbillon turntable with Ikeda 407 tonearm and Ikeda SAI cartridge and The Memory Player. The phono stage as well as the rest of the electronics from TubeGuru are among the best that I have heard. 

It looks alright, but I think you will find it underpowered for your speakers (I have T-3s which are the same impedance and efficiency). I assume your room is bigger than mine since you have room for the T-1s. I recommend something with 60 watts if you can (I run M-60s on mine most of the time which actually make 80 watts in the 16 ohm load of your speakers).

The other thing I think you will run into is that bottom octave issue. Your speakers go down to 20Hz, so something that can actually play 20Hz properly without rolloff is helpful. The amp in question has significant phase shift at 20Hz and so would come off with a lack of punch.

Finally, the 6C33 power tube eats tube sockets which thus have to be replaced on a service schedule unlike most other tube sockets. This is true of all amps that run this power tube so its not a condemnation of the amp in particular, just something to be aware of.
