Thanks advanced101 and spirit. Are these options known to be sonically superior or possibly offer greater flexibility?...in that the Ypsilon is factory-set. I now own the Kondo, and should it have the potential to bring out the best of the VPS-100, I may be able to swing the cost on a used unit.
The match of the SUT is with the cart, if you have that right all else should be good. I have the Kondo SFz with IO M and the Ypsilon and I hear no problems, the Ypsilon will tell you what is ahead in the chain. I have tried and used many other SUT's with the Ypsilon and never had any problems. Quality SUT's always shine through, some are better than others and if the SUT works well with your cart you will know that. Different characteristics come from different wire eg: silver vs copper, different ratios and maybe some have loading options.
I do not know anything about the Kondo SUT, but can give you the details of my Phasemation T-2000 SUTs (pair, one for each channel) so you can compare with that of the Kondo.
I use a set of Phasemation T-2000 SUTs with my Ypsilon VPS100. Phasemation says the best cartridge match would be 4 ohms, but also say anything with 1.5-40 ohms will work. The load impedance of the Ypsilon matches what Phasemation says is needed, i.e. 47k ohms. The T-2000 ratio/voltage gain is 26db and handles frequencies between 10-100kHz. The Phasemation works very well with the VPS100
Steveo, I don’t know if you’re still interested, but there is great information about SUTs on the second “Similar Threads” thread below; “Phono stages, SUTs, and cartridge loading …etc.“. Please check out #11 & #15 by bazelio, and #26 by Atmasphere as they might between them give you everything you need to know regarding SUTs.
The Emia SUT is supposed to be a great SUT. Steve Slagle (one of the owners of myemia.com). builds them to be a perfect match to your favorite cartridge. He uses 80% Nickel (aka Permalloy) transformers. He has two versions, copper or silver. The consensus on this forum is, the silver one sounds the best. They very rarely come up on the used market. He will even send you one to try built to your cartridges specs! They also have a great reputation for great customer service. Best of luck. Take care.
Thanks to all for the excellent input. I would ideally continue to use the Kondo, but Emia looks to be an affordable option. Regarding the Ypsilon, having no experience with it, does it perform to the level the reviewers claim? Any who may have compared it to Audionet PAM G2 w/EPX?
