I'm new on this site and I have read most of this thread because I'm a Chord fan after buying the Chord Qutest DAC, a few months ago. I really love this DAC in combination with my Yamaha A-S2100 amplifier and Revel F208 Speakers. So, I am interested in the Chord Hugo M scaler too, but it seems to me right now, it is not worth the money (4000 euro is a lot of money for any audio device, I think, except loudspeakers). It seems to me that that the M Scaler makes music a little better, but my recent investment in ifi iPurifier and if iPower devices is doing the same for far less money. I really think the M scaler is a nice addition if you can easely afford it, but for others, perhaps I should say 'normal people' it is just too expensive for what you are getting. I can afford it, but I'm very sure my wife would reject this investment, although she loves the Chord Qutest DAC. How about others in this thread, what is your opinion about price-quality?
