It can't be disabled Yep, just make sure that the amps don't have an unusually low input impedance, also keep both amps ON when playing. Some amps load the inputs when turned off and this could cause additional distortion including to the 2nd amp

Unfortunately not. IMO they absolutely should, and most professional oriented products as well as many high end DACS (RME, Benchmark, Chord, Ferrum etc) all have appropriate digital headroom management. BUT, many manufacturers like Topping, SMSL, Gustard that market heavily based on their SINAD...

Because as said, if you pad the Msb, you end up attenuating everything by 48dB

This is an example of intersample overs. The green squares represent the PCM samples. The green line represents the actual waveform once reconstructed: You can see that despite all the samples themselves being at or below 0dBfs, the waveform goes above it. To make it clearer here's the same...

The bit depth doesn't matter. max value at 16 bit is still max value at 24, 32 or 64 bit. Otherwise when playing 24 bit content you'd suddenly find everything was about 48dB quieter than 16 bit The issue is that if the source material has content that when reconstructed exceeds 0dBfs, your DAC...

I've not had a chance to test the 501/502 at home so can't say. Though analog attenuation wouldn't address the issue. It's the DAC itself that is clipping and once it's clipped that's it

In that case it's likely a network issue. How is your network set up? Due to some of the underlying protocols roon relies on if you have an unorthodox setup or are running via a vpn such as tailscale it may not see or be able to access devices even if the roon remote client itself is able to...

Is your pc seeing the DAC at all? Probably best first to determine if this is a roon issue or a hardware/setup issue

Make sure usb input is selected on the may. If it's set to i2s or coax or something the USB input is disabled entirely and the connected pc won't see it

If anyone wants a particularly good song to try the spatial enhancement with, give this a go: https://song.link/gb/i/1710738926

Yeah if you buy a brand new stock Wandla it'll have the voltage divider. If the dealer has old stock it wont

The upgrade will give you the spatial enhancement, impact+, tube mode, and the changes made to the DAC operation itself. Though you won't get the voltage divider option as that is a new hardware aspect.

:eyes: 465 is pretty damn fantastic

Yep! The spatial enhancement has separate speaker and headphone modes (I use speakers a lot myself, increasingly so these days) And the tube mode and impact+ mode are effectively 'playback method agnostic' and work great through both mediums

That's the intent yep! It doesn't alter FR at all, but adds some extra even order harmonics which make things a little warmer/weightier sounding overall. It's intentionally subtle so that it's not a party trick you use for 3 songs then turn off forever, but for either tracks or headphones that...
