In Stock form, the Uni transport is not good (signal degraded by the rats nest of traces to play back every format plus plenty nasty resistors in the RBCD audio path), but has great bones. Lukasz did many blog on his modification journeys. I am using a modded Denon (3910) myself with the wire...
I guess it depends on the quality of the laser pickup, how clean the signal trace in the transport is, the "stiffness" of the motor and the squareness of the wave of the digital output signal (as measured on an oscilloscope). Hence why converted universal machines are good value option. Those...
I would assume the biggest diff would be in the topology for the output scheme/tubes used. DHT circuit should be quite different. A possible analogy would be a v8 muscle car vs a high compression high HP inline 4 sports car.

Yep, I would go with position 3 too. The Dac will auto-correct as long as the total power draw is 8w or less. 01A uses minimal amps so it will get its needed 5v. I will again test to see if PX25 sounds better on Position 2 or 3.
I can imagine a very pleasing sound. I am not as fastidious as you are but I think I took a similar road leading to Rome. Lol. Heil speakers, Pacific, Rowen preamp and monoblocs. Tubes only in the Dac.
No chance to test yet, as I am in process of setting up a 2nd system with it as the lynchpin. My buddy says it rivals his Threshold pre , with a narrower soundstage, with a very decent Phonostage and great tonality. For the money, below $500 its a steal. Model is PE2217. Key is not to abuse the...
I recently picked up a Soundcraftsmen EQ/Preamp/phonostage for a cheap price in Europe. In the US prices are dirt cheap on occasion. Look into that. With mild EQ corrections you can dial in the speakers to adjust for the room dynamics.
Tube life extinction comes from the on/off cycling more than leaving it on. If you feel it’s safe enough, then leave it on continuously unless you know you won’t use for 3 days or more. Each on/off cycle introduces a molecule of air into the vacuum which eventually causes tube failure, that is...
Bal is only beneficial if your entire system is fully balanced, plus as Bonzo said, it’s more of a pain to roll 4 rather than 2 tubes. Bal Dac can run in SE mode of front tube pair are removed. On horizon you would remove the left pair, if I recall correctly.
