Burn-in period for Shanling CD-T100


How long should it take to 'burn-in' my Shanling CD-T100? I have the Western Electric 396's (NOS) installed. Also, are those upgrades for this CDP from Underwood, Parts Connexion, etc. worth the money? Thanks...

I agree with Tobias. I have a modified version that I recently had repaired. They replaced the DAC chips and it probably took at least 200 hours for the top end to open up completely. It's worth the wait.
Underwood mods-

When I had my Shanling I had Wally/Chris do the Level 1 mods and I did the OpAmp upgrade myself. The mods are definitely worth while.
I have the CD-T200 with the level 1 mods. I think it is very much worth the extra. Mine has a few hundred hours of play now and it just keeps getting better.
Thanks for the responses. At least I have some people here who like the Shanling - several trashed it in the 'Worst CDP heard' thread awhile back. Always good to have allies...
