I bought one of those a year ago and it’s worked well for me, but I’m feeding optical output into a Topping D90LE ES9038PRO LDAC I find is fine for my needs at the time, but I’ve been considering upgrading the DAC (denafrips 15th ed. Pontus or something like it) until I came across this today:
USB Type B (White): 44.1 kHz to 768 kHz – 16 bit to 32 bit
BNC Coax (Red): x 2, 44.1 kHz – 384 kHz – 16 bit to 32 bit
Dual data mode input (using both BNC coax inputs together): 44.1 kHz to 768 kHz – 16 bit to 32 bit
Optical (Green): 44.1 kHz to 96 kHz – 16 bit to 24 bit
Now, I don’t know if those are the absolute limits of the conductors or the particular DAC I was looking at (Chord Qutest), but it has me looking into cd transports with USB output FIRST.
YMMV. Feedback appreciated (although a little off-topic, I know), but from what that information is telling me - if accurate in general regarding connectors - I won’t be able to take advantage of a higher quality/performing DAC with the CXC.
The OP - and others, at this late date - might want to reconsider.
Please don't be mad at me, but I think you need to get to grips with the subject first.
Your Topping DAC can already do up to 32bit 768kHz via USB.
Which CD transport or player could you use to get more than the 44.1 kHz / 16 bit of normal CDs?
It doesn't matter whether you use USB, coax, i2s or anything else, you can't get more than 44.1 kHz / 16 bit from a normal CD. And the fact that upsampling or resampling doesn't help is nothing new anymore.
And just for better understanding, if you only drive on a bad and winding road where it is not possible to drive faster than 80 km/h, does it make any difference if your car could drive 100, 200, 300 or 400 km/h?
You can download samples from 96 kHz up to 768 kHz for free from Sound Liaison.
Do your own honest blind test with your Topping D90LE and the different formats and then please explain what difference it makes.
I can guarantee you two things from decades of experience.
The quality of the recording and mastering is x times more important for the sound than anything else, including your DAC or your CD transport.
Many people don't understand something simple. Your source, CD, file, record, etc., are your 100%. You can't make 101% out of that. But you can reduce it, and what's gone you can't get back, that's impossible.
Your DAC and your CD transport are likely to cause the least loss in your system.
