Hi Allan,

Cool links, thanks! I haven't been into solid state lately (gross understatement...) so these are very helpful.

I spent four hours listening last night, to determine the difference between two players (opamps vs. passive + transistor stage) and the winner is absolutely the transistor stage. The soundstage is more accurate, with better to pinpoint instruments. I thought I had lost some air or space, but it's there when it is supposed to be. With the opamps there seems to be more space all the time, and that sounds very cool at first. But it seems to lead to somekind of smearing in the soundstage, which makes everything less easy to pinpoint (am I still making sense???).

Regards,

Ray.

take a look at the LM394's dual matched.
old transistor still available, relatively cheap, saves matching transitors and i think pin compatable with bc54*/55* series
The MAT02's are newer devices, harder to get and pricey(for me)

allan
ps Yes your still making sense

Did my first coax upgrade. I did this one because it's the most important one, and because CDs were skipping a lot, and the sound was cutting out and giving me grief.

After some days of it not working (bird poo solder??) it's now working (sans-display, lol) and....

- the skipping is gone

- the timing, low bass impact and treble smoothness have been improved very nicely

Obviously I used an RCA so I can still easily dismantle the player.

I need to reduce the length of the wire

For the beginners amongst us - here's where the coax comes from on the transport pcb. I grounded it at this end only.
