Headphoneus Supremus
Just wanted to share some brief impressions since I had my first opportunity to spend extensive time with a Qutest and Hugo 2 today. I compared them exhaustively for almost 3 hours.
Gear used in different combinations:
- Hifiman HE1000se (with a Lazuli Reference cable)
- Chord Hugo 2
- Chord Qutest
- Wells Audio Milo Amp
- All power and RCA cables used were "high-end" (if you believe that cables matter, I do)
I'll give some context first. I went into today expecting to want to buy the Hugo 2 based on everything i've read. I mainly need a dedicated desktop DAC to serve both my headphones and speakers (I have a separate amp for the speakers), but the added benefit of mobility with the Hugo 2 is a nice plus. I love the Milo amp, but am not 100% committed to it if any of the Chord gear sounds better without it. In fact i'd love it if a chord amp drives the HE1000se well enough by itself that I can sell the Milo amp and put it towards other gear.
At the end of my listening session my order of preference of the gear combos I tried today (from most preferred to least preferred):
First Place: Qutest -> Milo -> HE1000se
Second Place: Hugo 2 -> HE1000se
Third Place: Hugo 2 -> Milo -> HE1000se
To my surprise the Qutest into my Milo amp was an easy winner for me. The sound sounded so lifelike, detailed and musical at the same time. Closing my eyes it truly transported me like I was sitting in a room with my own private concert! I really expected the Hugo 2 by itself to take first prize. I'm also very surprised that the Qutest + Milo sounded very different from the Hugo 2 + Milo.
The Hugo 2 alone sounded awesome and technically drove the HE1000se just fine (I can see why this is enough for many people), but it just didn't do it for me compared to the Qutest combo. The Qutest + Milo had a noticeably bigger soundstage, better 3D imaging, energy and just reached a bit deeper into the music for details. I really thought both DACs in conjunction with the amp would sound identical and that was not the case. If I absolutely needed portability I could be happy with just the Hugo 2, but that's not all that critical for me. My highest priority is what I hear as the best sound quality.
I am going to wait until I have a chance to demo the Hugo TT 2 in a few weeks to make a final purchase decision. But if I was to buy something today it would be the Qutest over the Hugo 2.
Hugo2 and Qutest have different analogue output stages so they would sound different. Qutest is based on Mojo's output stage (OP). See below:
Yes I too saw that... But 2 qute, although having a discrete op stage, is not powerful; it was never intended to drive any low impedance at all. Qutest op stage has been upgraded, but it's not the same as Hugo 2. The op impedance has not been measured, so any mention of it is an error. But I have increased the drive on the discrete op stage, and I have used the Mojo op stage. This has the benefit of being very small, but capable of delivering large currents. But let's be clear; qutest was designed as a DAC only! As an aside, the Mojo op stage is the same as Hugo 2 electronically, but differs with the packaging and power delivery of the op transistors.
