JVC "EXU-901a" (KRELL KPS-25sc Phase Tech CT-1 CT1) better than VAM1254, CDpro2LF ?

[OTK]

that DAC board is the new version for 25sc, there are 4 x BB PCM1704 dac chips. Its predecessor (25s) has UA-20400 dac modules (1pcs on each channel). As you can see on many published photos, Krell sold some units with mixed parts, for example: 25s unit with 25sc faceplate (I still own this version). If you need to replace laser pick up, you can use cheaper JVC units with Optima 4s pickups, but need to solve wiring, because genuine Optima 4 has very flexible thin wire, otherwise Optima 4s has sturdy cable wires which causes problems during pick up moving (too much force), so it is better to solder thinner - more flexible wires.
