MC Phono Pre Gain

At 0.15 mV that is pretty low output, even by LOMC standards. So you would likely want a fairly high gain phono preamp. I'd be worried about a phono pre with gain below 60dB (and even low 60s may be a touch problematic in certain set-ups).

BUT, this will also depend on the gain structure of the rest of your system. Where are you generally playing on your volume control dial? If you are between 7-10 o'clock on that dial and being higher on your dial doesn't introduce unwanted noise, then you might be able to get away with a lower gain phono pre.

I will let folks with experience with the DLS1 chime in on their recs.

I second Roscoeiii's response. With an output of 0.15 mV, you'd need about 67 dB of gain from your phono pre, give or take a few dB depending on the gain of your line pre. That is a lot to ask of the phono stage, and noise does become an issue with lesser designs.

For .15mv you need something that has a lot of gain and is very clean. My first choice would most likely be an Ayre 5 series phono preamp. Its dead silent and it sounds great. The Ayre is good enough that you probably will never have to upgrade.
