Solid State Phono Pre-amp Recommendations

Well, the Dyna P75 would be great with your Dyna carts, especially since your current one and the XX2 are low impedance. Love my SoundSmith rebuilt XX2 with the P75, which can be run in Phono Enhancer mode with it. Well worth trying out.

The Dynavector P75 mkII is a great phono stage and should work very well with your cartridges for obvious reasons. I wouldn't pass it over simply due to price. Not sure what your budget is.

I like the Sutherland PhD. You can find it used for about 1600.

I would also recommend the Parasound JC-3, I am running mine with a Delos and they work REALLY well together. Tons of gain and very quiet, good bass and lively fun sound.

My interest was also piqued by the Sutherland 20/20 but the JC-3 is too good to worry about buying anything else.

The ASR Basis Exclusive and Mini Basis seem to be well liked as well.

Also in the solid state category, the Einstein products seem to be well regarded.

I have owned a Sutherland 20/20 phono stage for a little over 2 months now; I play records most nights and on the weekends and I am still amazed and thrilled by the sound of all my vinyl.
The 20/20 is a quite flexible phono stage with regard to both gain, 5 settings from 40db to 64db in 6db steps and in loading also 5 settings as follows: 100,200, 475, 1000, 47,500 ohms. I run my Benz Micro Wood SL cart at 52db and 475 ohms & my vinyl sound far better than I have ever heard.
Even my old abused and hard used vinyl sounds better through the 20/20.
My system is as follows:
TT: Basis 2001 Signature with Basis Vector tone arm and Benz Micro Wood SL Cart.
Amp: Ayre V5X
Preamp: McIntosh C2200 used this phono stage (MM only) with a Benz ACE HO
previously and further in the past with a Grado Reference Master.
New & Current Phono pre-amp: Sutherland 20/20
Speakers: Maggies 3.6R
Cables: Transparent Audio

Good luck and I can add that I doubt that anyone moving up from a roughly $1K phono stage would not be delighted with the 20/20.I spent a lot of time researching phono stages without the ability to hear any of them and I find it hard to believe that any phono stage in the $2K to $2,500 range would beat the 20/20 in sound reproduction quality couple with all the flexibility the 20/20 offers. The professional reviews, they are out there, sold me and as did the flexibility built into the 20/20, which I value a lot. In addition Ron Sutherland, whom I do not know, but wrote to after buying his phono stage and asking a question was most accommodating and helpful. Strong support from the manufacturer is very important to me and this was supplied in abundance by Ron Sutherland himself, impressive.
I hope this helps you.
