Anyone upgrade from Jays CDT2MK3 to CDT3MK3?

Bummer, sorry to hear that. Email Alvin at Vinshine. One of the most helpful audio dealer out there. I do love my cdt2-mk3 so much, I have always resisted the temptation of the cdt3-mk3 upgrade. Your experience may be very helpful to others who may contemplate the upgrade. Good luck and keep us updated.

Try cleaning the lens with a q-tip and 91% isopropyl alcohol.

Important Note:

The Philips CD mechanism is a high-quality CD playback system recognized for its precision and sound quality. However, please note the following regarding its sensitivity to the type of discs used:

• Recordable Discs: CD-Rs and CD-RWs may present challenges, especially if they are of lower quality or poorly manufactured, which can lead to potential read errors.

• Vinyl Discs: While vinyl discs are not standard CDs, compatibility with hybrid formats or vinyl-like coatings can be inconsistent, potentially affecting playback reliability.

• Poor Reflectivity Discs: Discs with low reflectivity may hinder the laser's ability to read data effectively, resulting in skipping or failure to read.

In summary, while the Philips CD mechanism offers excellent sound quality, its sensitivity to disc quality can affect playback success, particularly with less reliable media.

The CDT2 and CDT3 both have Philips mechanism, but different models. Could that be the issue?

Yes, that could be some of it.  The CDT3 is 2500.00 more than the CDT2. I wouldn’t expect it to make three quarters of my CDs useless. I sold my CDT2 too quick I think.

stereophile magazine had a review that stated the CDT3 did very well when testing for skipping and far exceeded the standards for acceptance. I think I have a problem with this one.
