Spent about 4 months using phantoms, Leo and hugo2 as home set up. Have demo’d Sp1000 ss for a week. If it just down to sq the h2 is on a different page in this combination. Sp1000 is tebchnicalky very good, fairly neutral but doesn’t have weight of presentation, level of resolution and ultimately sounds far more natural, dynamic and pacey than sp1000. The Leo and phantoms play to all the h2’s strengths and enhance them keeping the beautiful natural sound intact and the Leo adds even more silliness to the treble and mids. I know Pete will suggest the ayre codex which by all accounts is great too but different and not really portable, so if the later doesn’t matter to you it has to be auditioned. The H2 for me had stopped the dac hunt in its tracks, there’s one caveat, it gets better, the better the source or transport you put in to it. The output as you’d expect is a result of a combination of the 2 not just the sig of the h2. Eg the results are better with my se100 than my iPhone and dx200 when used transports and it sounds incredible with the sp1000 too.....,that last comment doesn’t help at all but the h2 is just a digital to analogue converter and amplifier, an awesome one at that, but as such it is source dependent and while it’s a fine polisher of turds, if that’s all you put in ultimately thats all you’ll get out just presented in a prettier audio package.
