250 Pro vs. 250 Upgrade Review

[ogs]

Unfortunately, I’m still not getting the quality of sound out of my turntable that I’m hoping for. While this has nothing to do with the upgrade (the phono stage did not change), it just didn’t get any better. I have an Acoustic Signature WOW XL turntable with an Ortofon 2M cartridge. Not sure if the Devialet phono stage isn’t up to it or if I need to consider a different cartridge. But I digress.

Hi rbsound. I realize I am replying to an old post here, but did you find a way to improve the sound for vinyl? Your 2M cartridge is moving magnet and should see a load of 47kOhms or more. I believe the input impedance of Devialet's phono stage is max 14kOhms. A better match would be a high output moving coil for MM gain or a low output MC with the phono input set for higher gain. A step up transformer +low output MC +MM gain is an alternative (like f1eng is using), but a SUT is also generally designed for 47kOhm load so care should be taken here.
