I don't do reviews and other subjective armchair discussions about sound quality, but I just posted over on the N3 thread about an issue with the N3 that I noticed. In the processes of testing that issue, I built an A-B box so that I could truly test between the N3 and (X1-II/Fireface/828). It's simply a plastic box with a DPDT switch and 3x 1/8" jacks (out to hp, source 1, source 2). I wanted to verify what I was hearing was correct without having to pause, unhook, rehook, and play. I ended up copying the test files over to a few cards and shoving them into the N3 and X1-II.
The master (reference) file was played via foobar2000 direct to the DAW boxes. Of course, no EQ in the line, and at unity gain until the amp to the monitors, which are Genelec 8020 and Tannoy 501a. A pair of Sony MDR-7506 was also used directly off each DAWs headphone monitor amp and showed the same detail as the speakers.
Volume on both players was fairly similar. Again, this isn't about sound quality, but rather that certain tones didn't ring correctly. And on the N3, it didn't matter what volume or gain I used, the same tone appeared.
The N3 has much more clarity on the mids with a good presence, more "forward" than my calibrated studio monitors (and the stage was much more intimate with presence). The X1-II has a much wider soundstage and recesses the mids further away than the studio monitors with a bit less detail (vocal resonance).
The tracks I noticed the resonance issues on most are as follows:
- Rush, Limelight (The Spirit of Radio, 24-96 HDTracks) FLAC
- Dar Williams, Mercy of the Fallen (Beauty of the Rain, 24-88/DVD-A source) FLAC
- Kay Hanley, Fall (Cherry Marmalade, 16-44/CD) FLAC
These tracks on the N3, the drums and cymbals sound very plastic with missing resonance and reverberation. ... The drums don't have the proper reverberance showing up as a 'tap' and the cymbals come through as "ting" instead of showing the full splash. The ride cymbal also sounds very flat and has no resonance.
As an additional check, I put the same card into my Fiio X1-II with JH-5, UERR, and JH-16 (all full custom). It shows the drums at full resonance and the cymbals ring the same as on the Genelecs (with the obvious addition of clarity from the 8020s). But, the issue with the X1-II is that the cymbals came through sounding further separated and a bit louder. I had to engage the EQ and drop the 16K down 1db to get the cymbals to sound the same as the DAWs. So I would say that neither player is "neutral".
Again this isn't about the subjective feel or "what I think this sounds like" and isn't intended to be such. It was a diagnostic procedure for the N3 and I wanted to add the info here on the X1 thread in case somebody else who has both wanted to see if they noticed it too.
