Phono Stage upgrade to complement Dohmann Helix One Mk 2


Thanks to the recommendations from many users on this Audiogon blog, I think I was able to make a more informed purchase of a turntable, the Dohmann Helix One Mk 2.  I've really been enjoying the turntable for the past month!  

The next phase of my system now needs attention:  the phono stage.  Currently, I'm using a Manley Steelhead v2 running into an Ypsilon PST-100 Mk2 SE pre-amplifier (into Ypsilon Hyperion monoblocks, into Sound Lab M745PX electrostatic speakers). 

I've been told that I could really improve my system by upgrading the phono stage from the Manley Steelhead (although I've also been told that the Manley Steelhead is one of the best phono stages ever made).  
Interestingly, two of the top phono stages that I'm considering require a step-up transformer (SUT).  I'm not fully informed about any inherent advantages or disadvantages of using an SUT versus connecting directly to the phono stage itself.  

I suppose my current top two considerations for a phono stage are the Ypsilon VPS-100 and the EM/IA  LR Phono Corrector, both of which utilize an SUT.  I don't have a particular price range, but I find it hard to spend $100k on stereo components, so I'm probably looking in the $15k - $70k price range. 
Thanks.

You should put the Nagra Classic Phono on your audition list. I have heard they may be producing a High Definition Phono, which you may also want to consider.

Thanks for the recommendation, but it appears that the Nagra phono stage only has one MC input, and one MM input. To accommodate the Dohmann, I would need two MC inputs.

Just one man's opinion, but I have heard the Nagra, albeit not in a few years, and I do not think it would play in the league with Ypsilon, EMIA, and FM Acoustics.  Like I said, it's only my opinion.

drbond, I have not kept up with the latest and greatest in current-driven phono stages, but I had set my sights on the BMC MMCI Signature edition.  It's balanced and solid state.  I don't know whether it has been bettered in the last year or so. You might say it's too inexpensive for your category (~$5000).

I just got an older VPS.
It has 2x MC inputs, but I jumpered one to work as a MM.

I assume that a classic also can be gotten in 2x MC, with some extra coins.
(Just standard is 1xMM and 1xMC.)

The Classic is likely a step up, but my pockets are not as deep as I would like them to be.

You can likely have the Classic Phono customized. If not you can run a SUT into the MM phono. The Nagra Classic replaced the VPS in 2020 and is better than the VPS, which it replaced.

If Nagra releases a HD Phono, which seems likely given they just started making a turntable, I am sure it will be impressive, having heard the HD preamp and DAC.
