Metric Halo LIO-8/4p mkIV

I'm very pleased with my MH interface. High quality AD/DA conversion, lots of input/output formats, expansion cards, sturdy build quality, solid drivers and software, works with older Mac OS; preamps and DI are fantastic, you really get the full spectrum of sound, no noise, lots of gain, great clarity. Professional sound quality and features. Things that could be better? I think the DSP plugins are not in the same league as the best plugins (in particular the CS equalizer, the compressor/limiters, the reverb and the character), though the gate and Sontec EQ are really good; also, the front panel looks a bit outdated (in fact, it's from around 2009). Apart from these things, it's in my opinion one of the best audio interfaces out there, at any price.
