Bobs Device SKY 20 or A23 (Denon) SUT for my Charisma 103 cart

I will be adding a Step Up device to my system soon. It's an Amadeus table, Charisma 103, which has ruby cantilever, but nearly identical specs to a standard Denon 103. These will feed my Croft phono integrated driving Harbeth P3's. I'm leaning toward the SKY 20, but does anyone have any experience here. I'm a little surprised these units haven't been compared anywhere that I can find. Art Dudley did a write up on the Sky, but in the article he made reference only to A23 Homage SUT.  Cheers -Don

I would also consider the MFA 632 ($759) or if you can spring for it the Baby Classic ($1995) -- Jonathan does great work and can design the transformer to suit your specific needs. I have the Classic V2 and really love it -- but my dealer claims the Classic sounds better ...

Don,

A bit more expensive, but the second best transformer I have heard is from Auditorium 23 at about $1,000. The best being the Hommage

Best Regards,

Thanks for the advice so far. Bob (Bobs’ devices) carries my Charisma cartridge, and likes the Sky 20 for it. Then of course, the standard high impedance A23 is for the Denon 103. The MFA does indeed look interesting. The Baby Classic has great flexibility with adjustments, if I were to change my MC in the future. May be overkill for this system however.

Save yourself some money and look into the Audio Interface CST 80 SUT. Comes in a 40 Ohm or 1:10 version that is absolutely perfect for the 103. 

I have both the 40 Ohm and 3 Ohm versions and they are by far the best SUT I have ever owned.
