Hi.
I own a KTB (T1) for quite a while. Nice to see a T2P popping up. And thx for the review. It obviously helps to improve the product.
Do I understand it correctly that the coming T2P batches will have an option to get the Sabre and/or the onboard MCU programmed via XMOS?
One of the IMO major weaknesses of Tone1 was to not have direct access to the Sabre with its high quality internal volume control and filter settings via USB.
Having the Sabre VC accessible via USB would have quite some advantages. First of it's a high quality 32-bit VC. You could stream DSD and run volume control on it - no need for mediocre analog domain VC. You don't need a flimsy IR control and can run VC from your smartphone-app (in my case squeezelite-controller). Basically you could forget about the T2P control knob and IR.
@Gouwa - would be great if you could consider this, while working on firmware changes. I know it's possible. Others have done it!
Now. The jitter graph Amir presented looked a bit odd (off). I am wondering if that's related to the poor DPLL setting!?!?
@amirm
I read some "first listening impressions" about the T2P elsewhere. Overall quite positive I'd say. Confirming the rather good (and soon probably quite a bit better) measurements. It seems to me though that there's a joint impression in the air that the DAC lacks a bit
of "energy".
Since we are @ASR, there should be a kind of "scientific" explanation for "lack of energy", sometimes also called weight and body I guess.
When looking at the board layout I don't see much of buffer capacity close to the output stage. I am wondering how your
measurements would show such an, let's call it "transient response" (delivering enough energy at the right time) effect, or whatever you'd like to call it of such an analog output-stage?
Thx folks.
