vinilink Posted June 28, 2020 Share Posted June 28, 2020 1 hour ago, andyr said: We were playing an LP of Vivaldi's "Gloria". SQ improvements were: we could 'hear the room' better (the church the recording was made in). the decay of the vocals was longer lasting. My opinion of what caused these improvements? I have no idea - it simply shows that different power supplies have an effect on the sound - even though these power supplies are merely driving a TT motor. As does adding some isolation and filtering on the mains supply. Is this due to reduced wow & flutter? I wouldn't have thought so (we should played a piano recording.) Andy Easily noticeable in sound improvement when W & F are reduced. Link to comment Share on other sites More sharing options...

Andy I am not an expert as per se, but guess due to less fluctuation in power voltage will give far more consistency which will reduce in W & F dramatically, which in turn improves SQ.

I agree that power conditioning on an AC power feed to a motor speed controller should make the AC smoother - which could well result in better W & F numbers. Better W & F would certainly make sustained piano notes sound better ... but would it lead to the SQ improvements that we heard: we could 'hear the room' better (the church the recording was made in) the decay of the vocals was longer lasting?

Accuphase E-203, Denon DCD-1650AR, EM-Audio DAC (Japanese boutique), Denon DP-47F, Epos ES14, Canare digital interconnects, Bill's pure silver analog connects, musical fidelity speaker cables, Cardas power. Maybe speaker cables are to be the next upgrade. Edited July 5, 2020 by mexicoke68 17 Link to comment Share on other sites More sharing options...
