I have a pair of Conrad Johnson LP 260M SE'sNot really a speaker for tubes, bass will be hindered in the lower registers.
Stereophile test quote:
" However, the combination of 5 ohms magnitude and 45 degrees capacitive phase angle at 60Hz means that the LAT-1 requires a beefy amplifier (such as one of Krell's own)."
