Power Supply Comparison for Hugo M Scaler
Hi Everyone, I’d like to share some finding during my brief comparison of several power sources on the Hugo M Scaler
1. Poweradd Pilot Pro2.
I got this powerbank even before I bought my HMS with the hope that disconnecting it from the mainline will make it sound more heavenly. That hope just goes out the windows as this battery actually sound little brighter & grainier than stock SMPS
2. iFi iPower 12V.
I have to put decent effort to get my hands on these popular smps adapter as it wasn’t available in my country. My mind was filled with dream that by having it my HMS will perform way way beyond those HMS owned by fellow Head-Fiers. My dream was crushed. iPower is powerless against stock smps as it increased the brightness a bit.
3. SMPS that came with it.
With a risk of going against popular wisdom, I’d say this is the best sounding power supply on this comparison, the least brightness of them all and thus you get most natural presentation of sound
*Bonus 1: iPurifier 2 (dc barrel noise suppressor). Well, in my system it didn’t seem to purify anything, because it add a bit of brightness when plug into the SMPS’s barrel connector.
*Bonus 2: Nordost qrt qv2 (power conditioner). I plug this to the same distributor used by DAVE . This plug makes the bass a tad richer which could be pleasing on some record, but adding brightness at the top, so i take it out immediately.
I get two thing from this exercise. First the smps is surprisingly good and I probably should stay with it and don’t bother with replacement.
But it also show that HMS indeed responding to power supply change, so there is an opportunity that a better power supply will elevated it’s performance.
Other important thing I’d like to share is that I use 3 dedicated line for this exercise with arrangement as follow:
Line 1: Power amp only
Line 2: DAVE only
Line 3: HMS and PC (on this line I also have my router and tv and other non-audio stuff)
Somehow this particular setup gives me very smooth sound that makes it easier for me to spot any added brightness. In comparison when my DAVE, HMS, & PC were all connected to the same line, I struggled to hear differences between power supplys.
I haven’t try every permutation, but I suspect there’s still gain to be had by having the correct grouping or separating across different dedicated line.
Please note that I own and bought every gear being mention above, I do this comparison honestly with no intention to disparage any brand above, when a gear is underperform, it is me as a customer who take the most hit, a hit to my wallet and a bit on my pride.
Happy Listening to all
