Got the branded JVC today. Burned the first one & 1 from the middle if the cake. Unfortunately, these appear to be some of the worst TY's I've ever had. The first burn had 869 c1's, the second had 529. Both were 54 minutes.
My suspicion is the problem may be that JVC/TY is now using NO spacers at all in the factory sealed JVC cake, & the discs bounced around a bit in shipping. I remember a couple years back, when i got a pretty bad batch of TY premiums from CD Dimensions, "CD Sam" told me he suspected it was caused by at that time TY had gone to less spacers in the cakes. Again, this one had none.
They were factory sealed, & labeled as JVC Premium 52x. The discs were also labeled JVC. The mid is Taiyo Yuden.
The NOS TDK's from ebay are likely going to arrive tomorrow (if I can get to the post office in the snow!). Hopefully, they'll be higher quality.
