Mark Levinson 432 vs 532 vs 532H

Can anyone tell me the main difference in sound from these?
I have heard 532H at home, and I loved the sound, but I wonder if 432 is a better buy for the same price?
I can confirm that the 532 is analog, not switching like model 53, having seem them all disassembled. I spoke with some of the engineers behind the H series design and implementation, and while actually the PSU is smaller than prior ML products, its size, components and capabilities are founded in solid engineering and exhaustive listening tests. A lot of people even prefer the 532H sound than the 532. Oddly, even owning a 532 and a 533H I had not listened to them yet (moving out of country, so I will wait to get there) I listened model 53's with Salon 2 and with JBL Everest's at a Harman facility, and I can honestly said that they blew me away! I used to own a pair of B&W 802D, and I had to sell them just because of that particular experience. Never heard my speakers the same way after that afternoon with the Salon 2's and 53's. I found out that they used 2 532's as development amps while developing the Salon 2 (one for each speaker bi wired), which was what made me decide for it.

Sorry for all the ramblings!

Just today brought home my No 532 to replace my 532H.

The 532H is a great amplifier. I would have been happy to have it in my system for the long-term. However, an opportunity to purchase a 532 came up and I made the leap.

The 532 is brand new out of box, not broken in. The differences that I can hear so are:
1. better separation of every sound - highs are a bit clearer, background singers more distinct, highs have more "air" around them.

2. Lows are more well defined. Not that the 532H was a slouch at this, but bass is more defined and forceful.

3. Big picture: Some HD downloads from HD Tracks that were disappointing before sound better already, in the first hour of amplifier use - before any real break-in.

To be clear, I HIGHLY recommend the 532H as it was noticeably better than my Chord CPM 2600 integrated (no slacker on its own). I emphasize that I LOVED my Chord CPM 2600. It was easily livable and the 532H was better yet. Now, the 532 bests that.

I just think that 1 hour in, the No 532 is a noticeable step up from the 532H. Each individual should decide if the upgrade cost is worth the sonic improvement.
The No. 532H is a great amp. Don't worry about the chassis seeming sparse. The Chassis is designed to hold up to 5 channels of their newer compact design using numerous smaller capacitors instead of a couple large one's in the center. They're using two of their amplifiers for the 523H and two torrodial transformers for dual mono operation mounted vertically in the front, so it looks a bit sparse, but don't worry it's all about the sound. If anything it'll give more cooling space. The amp sounds like a good pair of monoblocks built into one chassis. It is fully differential balanced, so that can explain a bit of the price increase. It is a top notch stereo amplifier with an iron grip on the bass and exceptional soundstaging.   
My 532H arrived today. I switched out my Rogue Stereo 100 (which I really like) and installed the 532H into my rack. The preamp is a Sonic Frontiers Line 2 SE and the speakers are KEF Blade 2's.

It was one of those holy Mother Of God experiences!!! It was the best I have heard in my home in so many ways! Effortless power and dynamics, deep tight tuneful bass, pinpoint sound staging that was also deep and wide...

Compared to my more recent amplifiers (Rogue Stereo 100, Muse Model 160, Parasound Halo A21, & Sonic Frontiers Power 1), There was no contest! I think I may have found my "forever" amplifier!
Congratulations on your new No. 532. I know there are probably a lot of great or maybe even better power amplifiers out there but No. 532 is absolutely my holy grail amplifier. Enjoy.
