Power Amp advice

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.

I use this Mark 326s preamp with 201 power

Well, mixing oil with water was never successful.
I would recommend to go for Corus Rowland Preamp instead of the 625.

I use Parasound JC1's with a ML 326. Fantastic combination.

Of those you listed the only one I'd consider would be the Ayre, but I'd still choose my JC1's over it.

What speakers are you driving? What source components do you use? What sort of music do you like and at what volume? What are the dimensions of your room? It's pretty hard to suggest equipment without knowing those parameters.

Lloydelee, the ML 532H is a current product and a good one. I heard one driving Revel Salon 2s about a year ago when I was looking at those speakers (which I eventually bought). It was quite good in the mids. At the time I chose a Plinius SB-301 over it, as I found that the Plinius provided more dynamics and a more powerful, propulsive bass better suiting my listening tastes. But I might have opted for the 532H if the majority of my listening was say acoustic, chorale or small jazz combo music.

i used to listen to pop & vocal. My source is metronome cd4 speaker is westlake lc4.75. Room is around 100 sq ft. So,small size is preferred. tks.
