The Corda HA-2 MKII is probably to be reckoned with. I've compared the HA-2 MKI and MKII side by side and the difference was admittingly not huge but still relevant enough in contrast to the kind of differences you can yield from amp differences, which are not huge to begin with in my opinion. The new Prehead MKII sounds even better than the HA-2 MKII. I slightly preferred the Singlepower PPX3 with upgrades over the Corda HA-2 MKII but some other Headfiers at our mini-meet had contradicting opinions.
Personally, I'm not a big fan of the Gilmore amps' sound I've encountered so far. I've personally owned a Gilmore Lite and heard a balanced Dynamight (top of the line of Gilmore-design-based amp) on two occasions, once for several hours and with three different high end sources/ICs. In spite of the Dynamight's marvelous technical capabilities (soundstage, resolution, ...), the tone was somewhat cold and analytical. Therefore I like to think that there's no best at a given price point, it's all a matter of taste. For instance, from my experience, the Ray Samuels sound signature is distinctively different from the Gilmore sound so pick your weapon of choice. And I've yet to experience an amp that really owns its price bracket. Even the much rumoured SR-71, which was truly fantastic for a portable amp, was not out if this world compared to other $400 amps. For every giant killer, there's another one.
But for the type of sound you're looking for, I think the SR-71 fits the descrption of "on the slightly warmer side of neutral but still neutral" quite well. Very focused but still relaxed. I've never heard the HR-2 but if the tonal characters are similar, then it might well worth a consideration.
