Tube amps and ML speakers do NOT match! I have had CLS IIz's, SL3 and Aerius i's. The CLS IIz's were impossible to drive with anything and I had to use a pr of SF Power 3 to drive the SL3s. Tried using the assemblage 300Bs and the SL3's did not give out any sound at all!!! The Aerius was easier but it sounds dull with anything other than my then ML333 pumping 300Ws of Ssssolid Ssssstate power to them.
300B,811,211 SE triodes
Hi, the said tubes each have different sonic character. Read that 300B gives best vocals but lacks the bottom & top extensions. Not familiar with 811 or 211 except their higher power outputs. I intend to build a class A SE poweramp, preferably with single output tube. Speakers are Martin Logan Aerius of 89dB efficiency. Music preference is full range Jazz instruments & vocals. Please post your experience.
