there are levinson 436 monoblocks for sale at reasonable prices; a 334,335 amp would also be a good choice. IF you wanted to stay with ML. I would love to see a review of the ML-532 stereo amp as well- i would have to say that just from looking at it it's either a waste of money or it's one of the best stereo amps out there. as for the very latest amplifiers from ML they have gotten some favorable reviews but i am not aware of anyone comparing them to the Iron-Giant gear from a few years back.
Power Amp advice
My existing amps are Rowland concerto pre & 201 power amp. A few years ago, I also bought Mark Levinson 326s pre amp which now, I use this Mark 326s preamp with 201 power amp. Now, I want to upgrade my power amp. Could anyone give me some advice? Current options include, Ayre VXR, Rowland 625, Mark Levinson 532H. I have not tried all these, but, personally, from market comment, Ayre or Rowland are preferred, while, mark 532h's comment is not so good, but it has the advantage that, it comes from the same brand as my current 326s. Thanks
