We have had a pair of Vandie 2Ce Sigs in on trade and plugged them into our system for a few weeks. We enjoyed their presentation in our high end system as well as in the front channels of our home theater system.
Although we have not heard the 27.5, 331, 334, or 335 from ML, but we have had the opportunity to audition the ML No.33. These are very nice monoblock amplifiers. However, with the Von Schweikert VR-10s, they seemed to have been missing some musical depth and imaging, although their sure power was awesome (the fuses worked well also).
We have had received a very enjoyable music experience with the 2Ce Sigs connected to our reliable little gem that is built like a tank, the Clayton Audio S40 pure class A solid state stereo amplifier. The musical qualities were superb. Imaging, soundstaging, depth, clear vocals, smooth extended highs, tuneful and extended bass -a lively presentation that will get your feet a tappin'. The only thing that we feel could improve the sound with this lower efficiency speaker system is more power. The S40 ) only put out 80 wpc into 4 Ohms (the latest model s40 has 50 wpc into 8 Ohms, which ours only has 40 wpc into 8 Ohms). Good enough for a small room, but if you have a medium or large room, and play music at more than just moderate levels, more power is recommended.
The S40 and M100 have been reviewed in Sound Stage.
The Clayton M100 monos (100 wpc, pure class A) will close the gap on power requirements, and still offer the same musical signature as the S40. And the Clayton S2000 (250 wpc, pure class A, fully balanced stereo design) puts you even closer to a musical utopia.
We cannot comment on the Plinius, because we have not had the opportunity to audition this brand yet.
