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.

The only problem with FM Acoustics 122 Mk2 phono is it has a max gain of 56db only. While it goes well with its own high gain preamps, it can sound like lacking life and vigour through a regular preamp with 12-18db gain. It is not its true sound, but simply the gain structure issue. I have heard it doing that multiple times when paired with non FM preamps.

@rauliruegas forget about other Kondo models, they are average. Have you heard the GE10 ? I have heard it in a full FM acoustics system and compared with a FM 222 phono in the same system. 

@rauliruegas , I understand the Kondo sound you are talking about.

Thankfully the new generation Kondo has starkly moved towards accuracy and bandwidth extension. For example their legendary Ongaku is their old design. Refined, smooth, boring and laidback. But their new Gaku-Oh is totally a full frequency dynamic beast. The same is with GE10 phono. The only problem is people can't muster spending $60k on a MM only phonostage.

@drbond I have some experience with some of the phonostages you are considering (not all though). I used to own a EMIA CR phonostage and still have the EMIA SUT in my system. I have extensively heard the FM 122Mk2 in couple of my friend's systems. I have also heard the Boulder. But I have no experience with Steelhead and Ypsilon. As you might have already figured out, there are 2 ways of doing LOMC amplification. With SUT & without SUT (all electronic). Both camps have strong followings. IME, an all electronic phonostage with high dynamic range, low noise, low electronic artefacts is not an easy act. Very difficult in fact. Even a Pass Labs XP25 sounds better when paired with a well matched SUT into its MM input than its direct MC input. So even Nelson Pass struggles with it. Hence one should be very careful of choosing a high gain all electronic MC phono. There are many one-man brands which I call "designer" audiophile brands who make such exotic designs bypassing conventional methods. I stay away from them at least when choosing such sophisticated engineering hardware.

The EMIA CR that I had was good but had some dynamic compression which bothered me. Tonally too, it was not exactly neutral. The FM 122 Mk2 is very good. It has a solid state presentation but still one of the more complete sounding SS phonos I have heard. DSA phono was outright SS sounding, bam bam thank you mam types, lacked subtlety. The really good ones which are lifetime keepers are Kondo GE-10, Technical Brain TEQ-Zero, Silbatone SQ-107 & EMT JPA66 Mk3. These are my personal all time best phonostages to buy. Incidentally they all use SUTs.

BTW, I have also heard the FM 222 Mk2 extensively in an all FM system. It is very expensive and overall very good sounding too. Neutral and dynamic. But it lacks a bit of that final finesse in flow which allows you to melt into the musical piece. It is a weak complain though.
