HMS arrived on tuesday as expected at the shop, they hadn't it in stock and they received it the next day from the local swiss distributor. It couldn't be faster !
I've connected it to the system with the provided coax cable, the psu was connected to an emi/rfi filtered power strip (as the other non hifi psu are).
All is working fine without any dropout. Hadn't much time to enjoy it but I can say that the upgrade in sound quality is huge, as tested at the hifi shop on the Qutest. It's simple, I can't recognize my Qutest anymore with the HMS.
The first evening,like a dumb goat, I forgot to switch off the video filter, even like that the difference between 1M and passthrough was clear and big
(I'm still laughing about myself for that).
The HMS enhance the Qutest in passthrough mode versus my little USB streamer (Allo Usbridge), I've read here that "HMS is a RF killing machine", now I understand it.
May be the coax input on Qutest is better than USB, had just 2 weeks before a clear improvement using Allo Usbridge instead of the usb output of my dedicated Windows 10, fanless, ssd, computer powered by an HD Plex).
I will have soon more time to enjoy the M Scaler (without video filter on) during the next days, I'm very pleased with this addition to the Qutest after having a lot thought about doing it or not.
Rob Watts adviced me to go for the M Scaler with my Qutest and I don't regret it, this combo is amazing, it sounds thight and right with the extreme big depth holographic panorama it provides !
Cheers,
Nico
