Good day all. I'm looking for suggestions for a dac/pre amp combination. Preferably in one box to save space and plug sockets. Also must have an eq function, preferably either presets or manually adjustable. I'm not especially interested in using software. Final must is at least one analogue input. This is critical, I use a R2R and TT and my CD player, all via rca. (I want to eq those sources as well as any PC audio.) Budget less than £500. Any help is greatly appreciated.
You may consider narrowing your search to an amp with a 'simple' tone control - which should be easier to find.
It was Amir's recent review of the Fidelio X2Hr - in which he noticed a drastic loss of soundstage after digitally eq'ing the X2Hr - which made me reconsider my methods of eq'ing my phones. I had previously used digital EQ (PulseEffects) and analog EQ. (I've got two shelving Baxandall EQs/Tone controls with just a variable high shelf and a variable low shelf.)
To cut it short: I've switched off the digital EQ, and now I use only the Baxandall EQ/Tone Controls: It may be the 'most natural' intervention in the frequency response as it lowers (or boosts) a whole region (treble/bass) at the same amount.
Slight treble reductions of my HD600 or K702 or X2HR are sufficient. With the now famous Sony MDR-ZX110 ( I got it after Amir's review, and, indeed, midrange/vocals are great, great phones for the price) a slight treble boost is sufficient. Character of the phones is largely maintained (e.g. the soundstage of the X2Hr!).
A short research, maybe something like that:
Syba Sonic SD-DAC63106 Stereo 3 Band Tone Control Pre-amp and Headphone Amplifier

Can't say anything about the quality, 4 opamps is ok, such a device is not 'rocket science', there shouldn't be that much that can be done wrong - but who knows. The knobs seem to be bad, but should be replaceable by better ones (?). Maybe any member has got it, there seems to be a video.
I'd try it out - and send it back, if your not satisfied.
