The Twin Mark II's are often underestimated. The key to getting the most out of the Twins (like most speakers) is to find a good matching amplifier and cables. I am using an Audion Silver Knight single ended amplifier...in stereo mode...employing two PX25 tubes. Wiring is Audio Note Lexus and Acrotec interconnects to the digital end. The PX25 tube tends to produce a much leaner and tighter "bass response". I am only pushing 8 watts through the speakers, there is plenty of dynamics and the sound is glorious. The soundstage is vast, imaging is precise, and the lower mids are tight and fast. Also, I am using the Reynaud stands designed for these speakers...and yes, they do make a difference in tightening up the presentation and are well worth the investment. Bought them on Audiogon, brand new at a very fair price.
The man to speak to regarding Reynaud is the original importer, Randy Bankert, based in Toluca Lake, California. You will get an unbiased opinion from an audiophile who no longer has a stake in selling Reynaud products.
