  1. I have a full scarlatti stack fully optimised in every way, i heard the vivaldi in a controlled environment i know extremely well, and there is no discussion it takes only 2s to figure it out.
  2. I agree BUT Not sending the clock signal independently and recovering it from the audio signal is always going to be worst. It is a relative thing, If you have the opportunity to make the test it is totally obvious.
  3. Thanks, except people that buys the dCS Vivaldi Upsampler, it would be difficult to synchronise clocks across the Rendu and the DAC for maximum quality. in fact, the more i think about it, the more I think it would probable better to be Ethernet to Asynch USB2, so the clock can understand the sampling rate and propagate the right frequency everywhere.... the issue is annoying when using a computer with mixed sampling rate playlist because if your system is synchronised with a clock for ultimate quality, you need to dynamically switch clock base frequency automatically... anyway just my 2c
  4. Have you ever considered putting a BNC clock input as an option?<br>it would be very attractive.
  5. If i have correct information, it will be upgraded to do DoP in the future but not yet. dCS is in the process of upgrading the Scarlatti stack to DoP (the upsampler and the DAC) as we speak, the rest of the range will be done quicker and later. it is taking a long time because although vivaldi supports DoP since day one, the rest of the range is using different chips... I've been waiting eargerly...
  6. Miska, It is a very interesting setup you have, yes there surely benefit on the computer side, but you need to be able to strip down the windows/linux/macos to the bare minimum among of processes running in realtime. Lits of memory is obviously better for jitter, and "FOFIyng" data at the other end is indeed necessary but i would rather have a dedicated hardware for upsampling rather than software, a dedicated FPGA will always be faster and have more headroom and be less susceptible to computer issues.
  7. I would always do upsampling in hardware. i'm pretty sure upsampling in software creates software jitter even using memory play. in fact it is better to use to upsample to DSD outside the drive than to do it in the drive and output DSD from CD data. everything counts at this level of resolution. As for clocking, i can guarantee it will take you no more than 1mn to realise it is worth it! Even dithering is amazing concept but it works too. as a base case, the DAC is key, clock is next in my opinion. most people tend to dismiss the transport, but it is revelatory to use a dCS transport with an esoteric mechanism. If you have a lot of SACDs it is the only to use them properly unless you want to fiddle for weeks with an old PS3....
  8. Clocking has a incredible effect on the sound quality reproduction, but what makes dCS special is that only they've understood it (one of the very few companies that provides a complete clockable system, Esoteric and EMM and the only two others I can think of) but they went one step further by providing the ability to create calibrated noise to the clock signal, and this again raises the bar of sound reproduction, it is a bit counterintuitive at first. The Vivaldi system is not replacing the Scarlatti but sits above it. More importantly Vivaldi upsampler can be used with NAS, USB keys, etc... The system also support DXD (352.8khz) via Dual-AES and bye-bye Firewire (a good thing since it is so difficult to find good cables). All in all I think it is great that they are pushing the boundaries of what's possible, to give a car analogy, nobody is driving a F1 car but where would we be without F1? Personnally I looking forward to hearing the system even if I cannot afford the full stack.
