250 Pro vs. 250 Upgrade Review

[ogs]

As far as I have understood Devialet is somewhat 'diffuse' when asked questions about MM input impedance. The only measurement I know of is from the Stereophile follow-up review of the D-Premier. Quite old now, but lacking newer measurements it's the only thing we got. The Ortofon 2M is a good cartridge so should sound nice connected to a Devialet. When it doesn't, it certainly indicates that the loading parameters are wrong. We therefore must assume the phono input has not changed since the review in Stereophile.
