I'll post some pictures and a more detailed review later, but for now here are my initial impressions.
Although we had the HT3s and the HT8s there along with some Selah audio monitors the only thing we listened to with any amount of time were the HT8s. Bill's RA8s weren't yet completed and the 3s and Selah weren't really efficient enough for the tubes amps. At one point we tried going back to the SS amp, but we all loved the tube sound so much that we went back to the tubes quickly. In summary this turned out to be more of a music listening session than a comparison of speakers, although the simple fact that the 3s and the Selah weren't compatible with smaller tube amps was a comparison of sorts. I'm not sure of the actual wattage on the amps that we used, they were DIY and used two EL509s in conjunction with two EL34s (I think) in a push-pull configuration. I can say that the HT3s sound wonderfull in my house with a tube amp (Sonic Frontiers Power 2), but it has a lot of power (115 per side)
The sound of the HT8s with the tube amps was superb and emotionally engaging. I can only imagine what the RA8s and/or the new towers will sound like with the right amplification.
