hughjames SaidHi Andrea,
The TWTMC-PPG-V2 clock I bought from you a while back has made a fantastic improvement in my old Rotel CD player (used as a transport via spdif and I2S). CDs have never sounded so clean.
I’m scheming a similar upgrade to an old SACD/DVD player. I noticed that there was nothing on your web site for a 27 mhz clock. Is that by choice, or just out of stock?
If you don’t offer anything at 27 mhz, is there a chip oscillator (like the NDK ones) you would suggest?
Thanks,
Hugh
27 MHz oscillator was never ordered. We can build the DRIXO at 27 MHz, but the problem is the MOQ for the crystal, at least 10 pcs.
As an alternative I would suggest NDK oscillator if you can find one at 27 MHz.
