Well, I got the 2.4s, it was a whole day a driving to get them. Hooked them up and one speaker had one tweeter/mid unit not functioning. I auditioned these in a odd shaped untreated room, so It wasn't obvious to me one driver was broken. Kind of disappointing, but my fault for not being more careful; I did pay $1k so even considering having to repair them I still think am happy with them, the low price should have been an indicator something was fishy. I already contacted Rob Gillum and will be having the broken driver sorted, his quote for the rebuild of the driver seemed really fair and he got back to me immediately. I will be testing with a multimeter and hopefully its just the driver. The speakers cabinets are in pretty good shape, probably would rate the cabinets at 8/10. Based on a short audition, I noticed a few things. The amp was BAT vk-300x integrated and sounded very under-powered. The 2.4 sounded exactly like my 1.6 when they under powered. The overall sound was kind of hollow. The bass was there but there was no weight to it. The soundstage is there but not locked in solid. Not a good amp for the 2.4. Listening at home, with Coda amplifier these 2.4 speakers totally sang!!! They are so much more full and weighty compared to the 1.6, even with one tweeter not working the sound stage was huge and the treble was even smoother than the 1.6, maybe not quite as sweet but there was just more information coming through that sounded purer. I will update when everything is working fully, but I am already really loving these speakers. I really wish Thiel was still in buisness, they made some very special products.
