Sound Devices Mixpre6 Vs 633 On Loud Sources by George Vlad published on 2017-05-26T11:38:04Z A side by side comparison of loud sources: a water pump working, hand clapping. Recorded with Sennheiser MKH 8040 mics one next to the other in Rycote WS9. Left channel is the recording from the Mixpre 6, right channel is the one from the SD 633. Input gain levels were 72dB on both devices. Limiters engaged on the Mixpre 6, engaged as Soft Knee on the 633. Unprocessed audio.

I would be interested in the results. 2018-11-08T19:24:43Z Comment by AlbaSound Mastering Hi, in terms of pure audio quality (no limiters) - detail - noise/distortion etc... would you say that the mixpre6 is as good as the 622 and 702? 2018-01-30T14:25:17Z Comment by Chris Allan Tod thank you for the recording! the limiters are not the same and this way I can not judge the preamps quality. they sound totally different in this recording which is due to the fact that limiters are engagaed and the release time is different . I can not believe that 2 sd devices sound so differently 2017-05-27T21:21:07Z
