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?)

@czarivey Sure, and I could probably get a bigger improvement by replacing all of my gear entirely with different, more expensive things, but that's not really the point of this thread. 😂 I'm just curious about SUT options is all, and like Bill touched on in his comment - add 'another tool to the toolbox.' If I try a few and can perceive absolutely no difference, then that'll be the end of that.

There are in fact pre-phono preamps that do job of SUT a lot better and even worth a lot cheaper. dint ya kno that???

interesting theory…. this straight wire transformer…… i shall notify all those transformer engineers they have been doing it wrong all these many years…. except for @atmasphere …who for some crazy reason has worked very hard building amplifiers that….. ahem…. eliminate these perfectly transparent components…..

If you think this hysterical…. just alter the spelling…. slighlty….

not quite, I can compare MM with or without the SUT, I can only hear LOMC via the SUT.

""My different MM Cartridges, their differences similarly heard passed thru SUT or direct to mx110z’s MM Phono as above.

MC, the story is the same when listening to mine or friends (who are familiar with my system’s sound), theirs’s sound ’essentially’ like they are used to, the sound they preferred, not any noticeable alteration."

LOMC, I don’t know what my LOMC AT33PTG/II sounds like except the combo of FR SUT and McIntosh mx110z Phono RIAA EQ. Same for my AT33PTG/II LOMC Mono cartridge. My confidence that the SUT is not altering the Cartridge’s sound is from playing several of my friend’s LOMC cartridges here.

theirs’s sound ’essentially’ like they are used to the sound they preferred, not any noticeable alteration."

Get thee a tonearm with removable headshell, get thee some friends, get thee a true Mono Cartridge, get thee two tonearms, alternate ready to go!

I noticed, the ModWright has a rear switch: Stereo or Mono, which I suppose is like a Stereo/Mono switch on a preamp with that feature. It’s a feature loaded Phono Stage, I’d like to hear it here!!!!!!!!

Just as the OP said, SUT discussions are like drunken sailors, but remember, they get where they are going, usually.
