I see the LTA preamp only has RCA outs so maybe the balanced input is going to be louder. You might be better off going all RCA for consistency. It's not going to affect sound quality with short cables.
Do I Need A SUT
I recently moved from a PS Audio BHK Reference pre amp to an LTA ZTOL pre amp. I found the LTA pre amp to be more detailed slightly warmer and it just sounded better in my system. I also noticed a big difference in the output volumes between my digital rig and my analog rig. At the same volume level, my turntable volume is now much lower than my streamer volume, as opposed to the way it was before.
Analog gear - Technics SL-1200G turntable w/ Ortofon Quintet Black cartridge and PS Audio Stellar phono pre. Digital gear: Innous Zenith MK2, Matrix DDC, and PS Audio DirectStream DAC MK2. Power amp: PS Audio BHK250. Speakers: Tannoy DC8-Ti.
Before, I used all Transparent Super XLR balanced interconnects, except for the turntable RCA cable into the phono pre. Now, the only balanced cable is from my DAC to the ZTOL, which has only one XLR input. I replaced my Transparent XLR interconnects with Transparent super RCA interconnects.
Do I need a SUT to get a higher level of sound at a lower volume setting? My budget is $1,500. I know nothing about SUTs other than what I've read. I'm considering the Ortofon ST-7. Recommendations welcomed.

To the best of my knowledge, the Stellar phono stage has more than adequate gain for your Ortofon Quintet (Stellar offers 44 to 56db gain via MM inputs; 60 to 72db gain via MC inputs). Furthermore the LTA linestage adds additional gain to the signal passing through it. So, in a word, no, there is nothing to be gained by adding a SUT in between those two items. But you provide very little other information. Do you perceive a lack of overall gain in your phono system? How have you connected your phono cable (the output from the Quintet) to the phono inputs on the Stellar (MM or MC inputs, gain setting)? There seems to be a fad around using a SUT whether one needs to or not, which is nonsensical to me. If you notice that you have to re-adjust the attenuator(s) on the LTA for analog vs digital, that is quite the norm and not a reason for concern. Could possibly be ameliorated by choosing a higher gain setting on the Stellar. |
OK, so I don't need a SUT 😁! @lewm @jasonbourne71 Of the three gain levels on the Stellar, my system sounds best at the lower setting, which is the recommended setting for the LOMC Cadenza Black. The other two don't sound as smooth. I've also used Stellar's custom loading option set at 30Hz, but finally settled on 60Hz. @mashif I'm going to try the all RCA route, which should reduce the DSD output a bit. I've been playing the DAC at 90% volume level for years. If necessary, I'll futz with that some more to get the two a little closer together. Regarding LTA, you are correct. I live about 45 minutes from their office. It's always a pleasure going their - everyone is very nice, very accommodating, and fun to be around. Nicholas has been very accommodating, allowing me to home audition their preamps and power amps. I'm looking to audition their new DAC soon. Thanks everyone for your help! |
