Recommendations for MM Phono ~ Tube or Solid State

“active high gain phono stages are way better.”

@rauliruegas

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.

“optimal solution for MUSIC cartridge sound reproduction”

Our choices in gear and music are deeply personal and rooted in individual preferences, which doesn’t make us less capable of determining how music should sound—it just reinforces the idea that music reproduction is subjective. ‘Optimal’ is not a universal standard but rather what aligns with our personal vision of musicality. Some prioritize detail and accuracy, while others value warmth and emotional engagement. In the end, it’s about what moves us, not adhering to a singular definition of perfection.

While I appreciate your willingness to contribute, but I often find your approach a bit rigid and leaning heavily on the same perspectives. When someone seeks guidance, it’s crucial to explore diverse perspectives rather than defaulting to familiar responses.

When you post next time, keep in mind; encouraging exploration and informed decision-making helps everyone find what works best for their individual systems and musical preferences. A more open-minded approach could foster richer discussions and help others discover the best solutions for their unique needs.

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.

@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!

What if they are optimized for a specific cartridge along with rest of the components? And please don’t overlook or discount the user preferences.

@lalitk I probably have a skewed perspective as I have LPs that I recorded and I have the master tapes. So I know how those LPs are supposed to sound.

If the SUT is optimized for the cartridge and if its properly loaded it still will not have the bandwidth that you can get with an active phono section.

Years ago I found out how important bandwidth in this area can be; there was a phono section that came off as quite bright in a local dealer's showroom. They had us test it; what I found was the an extra timing constant had been added to the RIAA characteristic that caused it to go flat (so a 'zero' instead of a 'pole' for all you engineering types) at 50KHz. It caused phase shift down to about 5KHz. By removing it the phono section then sounded right, as well as measured right with the inverse RIAA network I used to test it; one of those cases where you could measure and hear what was going on.

Thank you for sharing your perspective. You may be right but I intend to test your findings by a/b both setups. I have no idea what equipments were used in your test setup. When I post my findings…I will post them with every component in my signal chain.
