Post Subject: 3 multibit DACsPosted by tuga on: 4/5/2008

Hi,

Last week I briefly compared my 47 non-oversampling DAC ("low performance" TDA1543), an original Teac player also used as transport (AD1862N-J ?) and a modified Akai (PCM63P or PCM56P ?). This comparison wasn't done with my single driver speaker system but with 3 way B&Ws. ;-)

The largest difference between the non-oversampling design and the other two was it's lack of air: it sounded as if someone had put a blanket over the tweeters... Imaging was closer to mono than stereo and low bass was a bit lacking, although I think that it performs better with the matching transport.

The Teac had more resolution(?) but sound a colourless in comparison, with a sparkly boom, tchiss, boom sound that would appeal millions... (bass was a monotonic sub-woofer like thingy).

The modified Akai had a more neutral tonality (the goal was to make it as transparent as possible), enormous resolution and an incredibly large contrast between pianos and fortes.

I would like to have the resolution of the latter with the SW (Kodak tm - saturated warm) thickness of the first.

I was told that the blanketness is a tademark of non-oversampling designs but I still have to listen to Audio Note's and AMR's players.

Cheers, Tuga
