  2. 👍 IMO, modern dacs seem to clean noise and manage jitter very well. These types of products, although very good and valid in certain scenarios, deliver little for dacs which already demonstrate great USB performance. Case in point topping d90, RME adi2 dac, newer schitt unison products. USB is slowly becoming the input of choice.
  3. IMO the RME doesn’t require a USB to spdif converter. The USB implementation is excellent by itself. The measurements and my ears tell me this. IME, USB converters can definitely change the sound, however it’s wasted money in this scenario.
  4. How much power one needs is dependant on so many factors. I suspect I would rarely if ever hit clipping, with my 20watts. Honestly, I'm not sure this is an issue everyone would have. Too many assumptions. For instance multiway amplifier setups reproducing small acoustic bandwidths would not suffer as much as full range amplifiers. High sensitivity setups also only require very few watts to operate optimally at very high SPL's. Distance to speakers, required SPL, room size, easy to drive impedance profiles, personal hearing etc all mean this position is not ne
  5. I suspect audible differences may exist between company input buffers. With Hypex and Purifi amplifiers measuring so cleanly, my suspicion is buffers will ultimately impact overall presentation. The buffer also plays a very important role if you are feeding via unbalanced RCA. The Neurochrome looks to provide a good grasp of what's required: https://neurochrome.com/products/purifi-1et400a-hypex-nc500-input-buffer
  6. Read this page from NP: https://6moons.com/industryfeatures/distortion/distortion_3.html
  7. Fair enough. I sit about 2.5m from speakers in nearfield. I typically listen between 75-85db, speakers are 94db sensitive. I would be interested in your feedback on the Purifi amplifier modules. Which brand did you go with?
  8. Although I agree, NP amps would clip with certain "nice sounding" characteristics, I 'feel' as a F7 owner it would be quite easy to hear the difference between an F7/J2 and a low distortion Hypex/Purifi operating below clipping. These amplifiers couldn't sound more different from one another. I.e. F7 smooth clipping: In any case I suspect most Firstwatt owners would be partnering their amplifiers with highly sensitive speakers, and therefore would spend very little time in clipping. For instance, with 94-95db sensitive speakers I probably spend most of my time in
  9. Googling Quboz, it seems Tidal have paid for a reference to Quboz in the paid search result. Does anyone else find this misleading...... ?
  10. So much has already been documented regarding the questionable "technical merits" and business objectives of MQA. IMO, MQA is a format we just don't need. Its a clear control and money play, benefiting a few, while delivering very little for consumers. I suspect and fear as more and more record labels jump on board, consumers will have increasingly less choice in what format they can stream. I just hope this madness doesn't impact alternative streaming services. IMO, MQA has nothing to do with better audio for consumers. As I see more and more Flac fi
  11. No issues. If you have a Roon stream playing, Spotify will connect and Roon will stop playing, and vice versa. Same experience with UPnP.
  12. IMO, I would start with a RPI4 running into a quality DAC. Its a low cost, low risk option. Additionally if you can, grab a decent supply which doesn't exhibit noise or leakage issues. Plenty have been measured for review. IMO, it makes far more sense to spend dollars on a good USB dac (and a sufficiently speedy Roon server), v's spending money on a high end Roon end point for the following reasons: - Modern DAC's reject jitter and noise much better than older DACs. This vastly minimises the impact of source on the conversion. - The RPI4 meas
  13. I sold a Pioneer n70a, which is a fantastic sounding streamer ($2500 at the time) in favour of my RME ADI2 Fs and RPI4 running Ropieee xl. This setup easily bested the Cambridge cxnv2 which I thought sounded horrible... My RPI4 connects via a Oyaide USB cable to my RME ADI and is powered by an ifi power x 5vdc supply. My RME ADI connects directly to my Firstwatt F7 amplifier as my Pre amp. The RPI4 is a fantastic sounding streamer and Roon endpoint When combined with a quality dac that exhibits low USB jitter, and noise management you’ll have a winner. Ropie
