Looking for SUT for Air Tight PC-1 supreme

For .4mV with 1 ohm, the maximum ratio is 1:25, if your phono overloads at 10mV. With MC cartridges, a basic starting point is to use an impedance of 10 times the internal impedance to be safe. Therefore the recommended loading will be anything over 10 ohms. There are exceptions like with Denon where lower impedance loads tame the high frequency response. So you will definitely be safe with 1:25 or 1:20. You might be fine with 1:30, if your phono preamp can handle 12mV without overloading.

I also have a Bob's Devices SUT. It is on of the best bargains in audio.

Thanks for all the comment. I am curious about B ob's Devices. The cinemag certainly has quite a bit of press lately but I am wondering if the Sowter might be a bit more flexible.Cinemag has either 1:16 or 1:30 with reflective loading of 184 ohms or 52 ohms (presumably too low for Air Tight recommended 100-800 ohms). The Sowter 1951 has either 1:10 or 1:20 so it is a bit more flexible as both 1:10 and 1:20 should work for Air Tight and it will be up to which loading sounds better with the cartridge. Anyhow, I am wondering if anyone has compare the sound of the Cinemag vs Sowter and what's your impression. Also has anyone ever compare either to Ortofon T100 by any chance?

Suteetat,

You might consider consulting Albert Porter's system page or pinging him...he runs an Air Tight Supreme, which sounded splendid when I heard it in his system :-)
