D class amps with Soundlab speakers

Hi: I heard the combo of Soundlab (model U1?) with two Spectron monoblocks with all upgardes and Joule-Electra Marienne-Electra full tube preamp. It was pure heaven. To begin with you got bass !!!! real bass. Did I say you get bass? Then the rest: gorgeous seductive midrange and silky highs. Huge soundstage (which you would get with your speakers anyway to be truthfull) and stunning imaging. Extraodinary detailed and yet "purely analog" sound.
This is one of very few combos equal (or may be even better then mine...). Soundlab (when driven correctly!!!!!) gives you real magic like M-A-G-I-K

Dob thanks for the feedback;I was starting to think it was a combination that may not be very good;I presently have m2's with upgrades and audiovalve challanger 180 monoblocks so I completely understand the magic that you are describing;thanks again.

Sound Labs do play nice bass. The trick is if the amp can deliver power into the bass frequencies as their impedance can be quite high. This is why they seem very power hungry if you have a transistor amplifier- an amp that makes 400 watts into 8 ohms will only make about 100 watts into the bass frequencies.

Its not a power issue though- 150 watts is plenty of power if the amplifier can make the power. Its a matter of impedance.
