Jim,
You will thoroughly enjoy the Decware - Omega combination. I have a relatively small listening room 15.5' long x 13.5' wide x 7' high. Tube heat from the amp (Decware SE84CS) is barely noticeable in summer, or winter for that matter. I sit about 8' away from the speakers.
The low-powered SET amp with Omega Alnico hemp drivers sound incredibly realistic. Very fast, with great tonality. I liked this combination SO MUCH I recently ordered a Decware Zen Mystery amp, CSP3 preamp, and a pair of Louis's Omega Super Alnico High Output 1.5 way-design tower speakers. My son is getting the current set up, boy is he excited.
NB
