Just put 50 hrs on mine and getting better.Have used the Ref phono which was no slouch but the new ph7 is quite a bit better in terms of overall resolution.It only has 57.5 db of gain so your cartridge output should be high enough to handle this baby.IMHO Audio Research has set a new standard in phono stage performance.
Any experience with the Audio Research PH7?
Please describe other similiarly priced phono stages you've compared to the ARC PH7 and in what context. Thanks!
