I still have 4,000 LPs and 2,000 78s in storage which I haven't auditioned yet. I have sold 18,000 LPs & 78s over the last 35 years. I made up my own criteria for keeping a recording-I have to want to play it 3 times annually (cannot be done in actuality as I have 25,000 LPs, 7,000 78s and 7,000 CDs).
My cable manufacturing friend has improved his CD playback immensely using his new COS Engineering H1 DAC. It beats the pants off our very analog (warm) sounding all in one CD players (EAR Acute and highly modified Pioneer DV 05). It could be that he added immense power supply caps, superior A/C cabling and vibration resistant material to the chassis to allow the dual laser Pioneer to track the CD more accurately. It beat out a Meridian Ultra DAC in a high end system with an Audio Research CD transport (a recent player).
My other friend Frank/Oregonpapa has extremely modified the same Pioneer DV-05 with Synergistic Research fuses and PP total contact, omega e-mats and now the gate to also wildly improve his CD sound to high end status.
