SUT help


Hello all,

I've combed the forums and pretty much every SUT thread either devolves into arguments of the merits for/against, or gets hyper specific. I'm assuming to properly match a SUT, it needs to be selected based on the cartridge AND phono pre-amp. Since I haven't found a thread about my specific combo...here I am.

I don't know a TON about SUTs, but I'd like to experiment to see if adding one will enhance my experience.

Currently, my cartridge is a Hana ML and my phono pre-amp is the Modwright PH 9.0XT. I may possibly move up to the Hana Umami Red in the nearish future, but the specs are fairly similar between that and the ML.

Hana ML specs: 0.4mv; 7 ohm/1khz
Hana Umami Red specs: 0.4mv; 6 ohm/1khz

Modwright PH 9.0xt - MM input is 52db gain, with option to lower -6 and -12 to 46db and 40db.

I currently use the MC input which offers 64db of gain (-6, -12). I've typically kept it at 64db and alternate between 100ohm and 250ohm for load impedance settings. The 470 is too much.

Not sure if its possible to have a SUT that would work well with both the ML and umami red, but if so, I'm all ears. If not and they each need specific ones, I'd be considering the ML first and foremost.

Any help is appreciated. I don't really have any clue how to determine what ratio is best and whether copper or silver pair better with these cartridges. I had EM/IA recommended to me in the past, but their pricing is well beyond what I'd like to spend on one (~$1500 or less, ideally?)

@theflattire interesting!

I'm definitely considering the Umami (though I also thought about the Etsuro Cobalt) but I struggle spending $4k (or $6k) on a cart that will have to be replaced every couple years due to wear. The trade in is a 30% discount toward a new one, but still. That's a pretty high recurring cost. Whereas something like a SUT if it offered any improvement lasts pretty much forever. That was my logic, at least. haha.

Side note, it's a bummer that Koetsu is no more. Good thing you got one while you still can!

In my opinion, if you are dissatisfied with the SUTs that are built into the Modwright, you ought to talk to Modwright about having them install a better pair of SUTs. You would have pretty much the same array of choices, you probably will save money because you don't have to pay for the box that houses the SUTs, you probably gain some advantage over any external SUTs in that you avoid another set of RCA connectors and wires with capacitance in the signal path, It's a win, win, win proposition.  After all, Modwright made their bones by modifying gear built by other companies; surely they can do the same for their own gear.

@mmcgill829 As Stated, I have experienced many SUT's, a large selection of these on the home system, that are with retail Values of Approx' £300 - £2K and maybe even more expensive if listened to in other systems.

These SUT's are designs no longer produced, through to available designs.

Additionally, I have experiences SUT's that are produced using Tranx's referred to above and others, that have been utilised as a DIY Build.

As a result of Phonostage Bake Off's attended, I have experienced many Phon's used with a In Built MC Stage and a MM Stage with a SUT.

From a large range of experiences, I have not experienced too many SUT's I have thoroughly enjoyed and could live with.

Also when a SUT has been of real Interest, it is because it has produced something in the end sonic, that is much more wanted to be maintained than the MC Input can achieve.

As an individual with an all Valve System and a main Phon' being Valve Input / Valve Output design, along with Phon No 2 being a Valve Hybrid, I have selected SUT's that are in your description in the range of being Neutral. ( Richness being detected is a unique preference, it causes endless debate or blatant rejection, I've seen this regular in Group Assessments. One's own Get of the Bus point for a Tone is another's that is classed as best avoided).

The idea of having the Tranx's placed within the Phon' is an OK idea, but will be limiting to your experiencing SUT's or Head Amp's if they become a device of interest. 

The Sculpture A has been referred to above, I have been demo'd these in both Copper and Silver Coil Tranx's and have been so impressed, these are on my must try in the home system short list, not much gets on to that list today.

A thread about SUT's and produced by a Forum member who's posts are looked forward to by myself is attached.

  

 

Your MC stage of your Phono Stage IS A SUT.

ALL MC low signal in/MM strength out are SUTs.

Your Phono has a terrific set of optional Loading:

ModWright PH 9.0

MC Loading: 10-20-50-100-250-470

And, independent and adjustable gain is the holy grail IMO.

.............................

IOW, you already have an EXCELLENT SUT

and, SUTs are not supposed to have a sound, exactly the opposite, just step it up without changing the sound of the cartridge or the sound of the MM Phono Stage.

....................................

Additional Cartridges: the sound of any cartridge you have/get needs to get thru a SUT without alteration. I’d put money on the fact that your ModWright does just that.

Aside from researching/considering any cartridge's sound characteristics, which are ’preferred, not better’, I always encourage looking for technical specs: wide channel separation, and tight channel balance, the combo yields terrific imaging of the ’preferred’ cartridge sound.
