I also "feel" that the 3160 is the first SS phono/linestage that ever made me forget I am listening to SS. Dare I say it’s very similar in SQ to my modified MP1 (which might upset Raul but which I mean as a compliment). I love them both. As you know, this is coming from a tube OTL guy.
@lewm One of these days you might want to hear what happens when you parallel more tube sections at the input of the MP-1 phono section, and then give the gain stages a better CCS circuit.
While I understand your preference for active high-gain phono stages and recognize the strengths you’ve highlighted, I believe it’s important to acknowledge that audio reproduction is highly subjective. SUT’s may not align with your experience of optimal sound, but they can offer unique qualities that others might prefer.
@lalitk Raul is right on this one. I hate to put it this way, but what you’re talking about has to do with what you’ve heard and also what you’ve not heard. SUTs, like active electronics, are not all the same. But if you hear an active phono section that has the gain and is really competent, its a pretty good bet you’ll change your thinking.
What is probably poorly understood in general is how wide the LP bandwidth really is. Its wider than analog tape even at 30 i.p.s. and wider than digital. Its also wider than most SUTs. Its not wider than a competent phono section. Bandwidth can be really audible due to a phenomena called phase shift, which occurs at the top and bottom limits of any audio device. If the device is passive, as in the case of an SUT, phase shift components can occur up to 10x the lower cutoff frequency or down 1/10th the upper cutoff frequency if the device rolls off on a 6dB/octave slope.
The ear converts phase shift over a range of frequencies to a tonality. So subjectively you hear the limits of an SUT as a lack of bass (even if its flat to 20Hz) and a bit of a darkness in the highs. This is of course highly variable with each SUT! Something to keep in mind with SUTs is that they are transformers, and so transform impedance. What this means is that if you change the cartridge, the correct load to prevent the transformer from ringing (distorting) changes too. BTW if the SUT is ringing, it will sound brighter despite not having much bandwidth past 20KHz.
Its that last bit that means that a lot of SUT setups are not optimized!
