E50 auto On/Off function, it will automatically turn on and set to the input which the signal is valid. And when the signal of E50's selection is not valid for 1 minute, E50 will turn off automatically.

Topping E50 supports an automatic on/off function, it automatically turns on and is set to the input where a valid signal is found. When no signal is provided for about a minute, the E50 turns off automatically. I've supplied my DAC with 5 volts of 'dirty' USB power, switched mode power, linear power and, the cleanest, D.C. power from a battery.Edit, after googling. I see it’s Class D. 124db SNR! Never heard about such high numbers. Probably why it’s so quite. Hi, I recently upgraded my system to a pair of Q Acoustics 3050i and a Rega IO as per great suggestion on this forum. Very happy with them but since then I had the suspicion that my IFI Zen is actually a weak link on the whole thing. StereoNET (United Kingdom) is part of an international network of publications owned wholly by Sound Media International Pty Ltd Literally nothing to tell. It sounds entirely transparent and thus, boring if you want character. My valve amps are not very valvey by the standards of the breed, but switching the Klipsch Fortes between full range and bass managed always made for a softer bottom end.

This also makes E50 suitable for applications: high-fidelity PC-HIFI system, mobile phone/tablet OTG, CD player/turntable external DAC, digital broadcasting external DAC, TV DAC, and so on. Alas, I just have to say it.. I HATE not having XLR for balanced duty (both input and output), I really like how solid and instant a connection is with XLR. I can somewhat understand for portable devices that use 4.4 or 2.5mm (though 2.5mm creator should be flogged, it's far too fragile at that size). One of the internet radio services - TuneIn, etc. As long as you can get access to BBC and country/regional radio services for where you are.

All the 5V have smaller plugs but I found a Linear Power Supply with the right plug... but it's 12v Had no idea I had one of those but apparently that's what my router uses. You weren't very far off there, every time I ask for an opinion on something on a forum I end up blowing a lot more money than I initially was considering!

|Headphones: Sennheiser HD660S2 | HIFIMAN Sundara | AirPods Pro 2 | Audio Technica ATH-M50X | AKG K371 | Sennheiser HD380 Pro What can I say but another star performance from Topping. Company is so focused on squeezing every bit of noise and distortion out of these products while providing them to us at bargain prices. And in this case, great looks as well. I wish I could complain about something but nothing comes to mind.Bass is firm and tight, and the amplifier encompasses dynamic extremes without obvious signs of strain. Compared to my regular amplifier, the overall presentation was just a little drier and not quite so sweet and relaxed. But after I'd listened for an hour or more, this early impression became less and less noticeable as the ear acclimatised. Acoustic space and the position of instruments in it (however artificially engineered) seems cavernous and more precise. The valves closer and slightly softer. You can already listen to 24 bit music for decades. You don't need true 24 bit resolution for that. You can't hear -120 dB signals in music anyway (if it could be recorded in real life situations anyway). The little E50 is based around the ESS ES6068AS DAC chip, which includes MQA decoding. This handles PCM from 44.1kHz to 768kHz, in 16- or 32-bit resolution, plus DSD up to DSD512 spec (native) and up to DSD256 (DoP). It has an automatic on and off mode, so sleeps after one minute of no signal being detected and then powers up again when one is found. Its digital volume control means it can be used as a preamp but can also be set to output line level where no needless attenuation is applied. Hi @Tinman1952 , no I haven't... I keep reading it makes no difference or very little difference. I'm inclined to believe it does something, the same way dacs don't all sound the same.
