My Audioquest cables fit HUGO without any problems, but "the other Chord company's" cables are a pain to connect.
I have the Chord (Company) Clearway RCA pair. No problems with fitting. I love it.
It's already sounding much better, and I'm now at the 1 week mark!
Good recordings really shine with the H2, while mediocre recordings don't benefit as much from it.
It will only get better. That's what I think and I mean only to be honest.
I actually found that the Hugo 2 does good with poorer quality recordings. I was saying quite a few weeks/pages ago, that my copy of Shirley Bassey CDs sound good with the Hugo 2. They are recording from the 70s so quite well made, but they sound a bit old. I bought a double CD of two albums together. Good, Bad, but Beautiful .. and .. Never Never Never, sound really good with the Hugo 2. .... Songs like No Regrets, and Shirley's tone, the timbre of her voice are compelling, even though the recording sounds dated. Send in the Clowns of course is always going to be a special one from her. Shirley's voice is so smooth and soothing.
Anyway I am in rambling on territory here. Just wait until you have become fully accustomed to the Hugo 2. I'd say be prepared to wait even a month until you know what the Hugo 2 can do. I mean so you're listening to the Hugo 2 without thinking about it. In other words, you're listening to the music, rather than analysing the Hugo 2 sound quality. .......... Having said all this, I loved the Hugo 2 from day one. Initially I found it expertly detailed, impeccably neutral, and with natural warmth. However I need time to adjust to the more advanced 3D sound that the Hugo 2 makes. (On amplifier and speakers.) I upgraded from the Mojo, so I knew what to expect, and that it would take a while. Since it took a while to totally get used to the Mojo.
For me it took about two weeks, but a bit more maybe to completely relax. (I didn't analyse because I bought it from pro-reviews, and was sold from moment one of listening.) ... However another aspect to consider in how long it took me was this. I listened to the Hugo 2 non-stop when I bought. I was feeling that life was far to short not to be listening to it. The Hugo 2 might take someone else longer or shorter, to get used to, but I don't know.
