I've owned this CD player for over a year and it has sounded fantastic. Couple weeks ago, cranked it up for some friends and it sounded harsh and distorted at times. I rolled in some other Russian 12AX7 tubes and removed the cages, thought it was fixed, but again, strident highs and unclear bass at volume.
Did a comparison with my tried and true Carver SDA carousel and the Carver was sounding better. I have now put a single play Onkyo in the system to make sure the cables or other downstream components were not suspect and the Onkyo sounds good and clean.
I'm using my Polk SDA SRS 1.2 TLs; Sunfire 300x2 amp on the lows; pair of McIntosh MC30 monoblocks up top and those tubes are all good, no issues. Running other sources like my Rega or Marantz 6300 TTs, sound great. I do think I have isolated it to the Jolida.
Any thoughts here on what may be wrong with the Jolida or next steps? Any known issues with them? I really like the Jolida, well built and sounded great up to this point, kinda stumped on what went wrong or why.
Thanks in advance for the assistance guys!
