I am currently using a just completed EHHA rev. A as the headphone amp, which is why I am able to change input impedances so easily. Based on what I am hearing so far, I think I need a better headphone amp... I am sure Concero can sound better than what I am hearing at the moment. Next on the build list was a Bijou, but I am not sure Bijou and Concero will play nice with each other as they are both on the smooth side. Maybe something solid state would work better.
The EHHA is a nice amp but I agree that you can do better - Concero is surprisingly capable in terms of not being the weakest link among fairly expensive gear.
Great thread everyone. I've been reading with interest. I'm in the process of upgrading my system and adding a computer-based capability. I'm researching DACs in the sub $750 range and have stumbled upon this Concero as an interesting option. I'm acutely aware of good system matching - but am by no means an expert. My setup won't be including a headphone rig for now, but instead has an EL34 tube integrated and some tube-friendly tower speakers. The speakers are fairly neutral across the frequency range - with perhaps a slight bump after 5kHz, but it's very minor.
So, with all this in mind - What would be the "better" match - the Concero or something like the Yulong D18? From what I've been reading (and I haven't heard either at this point), the Concero is more neutral, while the D18 is warmer. Now, I enjoy the warmth of the tubes....but don't want to overdo it, and lose too much detail etc. On the other hand, I don't want something that will over-brighten the system either. Any help would be greatly appreciated.
Having both here to play with, I'd say it really depends on a few things. First - what's your plan for getting a signal from computer to the D18? Because depending on the direction you go with that, it could make the D18 a considerably more expensive choice.
I doubt either option would push things into overly-bright territory. Concero is neutral-smooth and D18 is warm-smooth, with bigger bass and a larger soundstage but less detail. Honestly, either could probably satisfy.
