How do you tame a Denon DL-S1?


I recently got a Denon DL-S1. It has a very low output. I have a Minimax phono preamp and a Dodd. I have been rolling tubes and trying various things to see what works best with the Denon. When I use the stock JJ 6922 tubes in my Dodd and run the Denon directly into the 47k input, the detail and texture of the voice is unbelievable. I didn’t know there was that much information in the grooves. The problem is that I have to run the gain of my preamp up so high and the overall tone is not quite as good as with 60’s Amperexs or the Sovtek 6922s. With the other two I lose a lot of the detail and texture. My question is; would a SUT give me more gain and still keep the detail and texture? Would the SUT improve the overall tone? Would a blue Cinemag be a good choice?

I suspect that it might be a similar problem to other high information mc cartridges

You need additional gain, so you have three options: 1/ add a step-up transformer, 2/ add an active pre-preamplifier, 3/ get a preamp with a MC input with the two gain stages you need internally cascaded.

Loading requirements are different for SUT and for active amplification, since the cartridge doesn't see a simple resistor the same electrically, across the audio bandwidth, as a transformer. I generally agree that loading the DL-S1 somewhat higher than Denon recommends will be your preference but there's a lot of latitude for experimentation between 40-1000 ohms.

I have both active and Xformer step-ups in my various phono systems. I don't even slightly agree that the cartridge's full potential can't be extracted via SUT, but it is a matter of getting the right one. Denon's own transformers aren't best for this. The Cinemag (blue) SUT that Bob's Devices sells, and the EAR MC3 or MC4 do the job well, at disparate price points. As for a quiet, stable, revelatory companion active phono stage that has the gain you need, I can recommend the Jasmine LP2.0 (70db total gain), and the Bel Canto Phono3 or the older Phono1. All three are solid state and I know personally they mate well with the DL-S1 and sound good.

The Jasmine looks interesting. I see the MC gain section is in two copper boxes. I wonder what is in those boxes? Transformers?

Based on positive listening experiences at shows, I suggest Pass Labs XP-15 or XP-25 phono stages. These do 76db gain with granular loading options all the way down to 10R.

That's shielding. Gain is active, and it sounds astonishingly good, regardless of its affordability.

Dear Rsimms: IMHO Dgarretson advise on Threshold is a good one and has not SUTs but pure active high gain low noise stages.

Regards and enjoy the music,
