white filter is the most neutral, correct? just got ch2 and listening

Yes. It's the same as the Dave and Hugo 1 linear phase filter AFAIK.

Does it need to set Hugo2 to the line level mode also or not

No. Line level mode is just a volume level. It's often too high for the inputs of other amps. Just set the Hugo 2's volume at a level suitable for whatever you want to do, eg: Whether or not you want to use the volume control on the amp, for example.

can i just check the remote control only switches hugo 2 off? to power on you must press power button i.e. the remote does not switch hugo 2 on.



concerning white H2 filter--quote--"Yes. It's the same as the Dave and Hugo 1 linear phase filter AFAIK." true answer-- similar to dave in tonal quality and balance and nothing in common with Hugo1.

The remote turns it off and on...at least it does with mine.

Just to clarify - Hugo WTA filters were in two stages, WTA 1 which went from 44.1 (1FS) to 352.8 kHz (8FS) and was 26,368 taps. Then WTA 2 took you from 352.8 kHz (8FS) to 705.6 kHz (16FS).

With Hugo 2 on the other hand, I have a much more powerful FPGA, so I can do more processing to get one closer to the original signal in the ADC before it was sampled. And with Hugo 2 WTA 1 took you right away to 16FS, so it went from 1FS to 16FS in a single WTA filter; and this is 49,152 taps. Then WTA 2 is quite a complex filter, with 6 DSP cores alone, and takes you from 16 FS to 256 FS, so now the WTA output is every 88 nS. When you switch from orange/red to white/green, then you are engaging this filter.

So Hugo to Hugo 2 is a very different and much more advanced WTA filter topology.

Thanks Rob. Can you clarify if the all the filters will have an affect irrespective of the 'bit' quality of the music being played.

So will all four filters have an affect on the sound of an MP3 file, CD or Hires, of do the White/green filters only impact hires music?

Thanks

PS - Hugo2 = great sound -:)

The filters do not "know" what the source is; they treat 16 bit and 24 bit in exactly the same way (actually 16 bit is 24 bit set up as the bottom 8 bits being all zeroes), and can't possibly know whether the PCM was originally MP3, AAC or straight uncompressed PCM.

Of course they know what the incoming sample rate is...
