Cost effective mods for a Sony SCD-777ES

Wow. Lots of great advice. Thanks everyone. I am Mr. Conservative. I am very nervous to spend - $1,000 and not be able to get it back when I sell it. I think I will buy an external DAC rather than continue to modify it. Mine has Black gate capacitors and Vishay resistors. I will leave it at this level. Any suggestions for external DACs. My local tweak guy says - use a modded Bel Canto DAC 1?

I agree - Tvad. Mine did not have as many Kern mods as the one on sale know. That is OK. There is no doubt in my mind that the transport is excellent. Playing with different DACs can become a new interesting aspect to get the sound right. A friend of mine has a Meridian 566 - 24 bit. Let me start there.

I spoke to a reputable modifier - xxxx last night. Their opinion was, the SCD-777ES is already good (I agree)and the risk that something happens if one ships a heavy player like this back and forth or breaks by age is too large. Obviously, it is not worth to have to buy a second player to keep a stock of spare parts. In summary keep the player "as is".
