JMHO for me the modded 800 with BA were better than the BH/007mk1 or KGSS/007mk1. I love the 007, they will always have a special spot, just like the SR-O. I've had a chance to hear the 009 with BH in quiet settings on a few occasions and they never moved me. Even when PJ had them for as low as $3300 I didn't feel I wanted to buy one. Stax did something really right with the SR-O, black magic or whatever
With the Gilmore Lite I don't think the 800 are as special. I'm not sure if it's the DHTyness of the BA or higher output Z, but that combo clicks for me.
