Odyssey Stratus or Parasound Halo A23?

I agree with you. I have 2 sets of M200's and a 202plus and my son just bought a used M200. Their sound for the bargain price is unmatched. Pairing them with a tubed preamp AI and they really sing. Sadly, I just checked and saw none for sale on Audiogon or Ebay.

Comparison of Stratus vs B&K monoblocks follow:
Objective Specifications:
Price: B&K Used $600-750; Stratus new $2150 used ?
Power rating: B&K 200W; Stratus 180W
Amp output B&K 150; Stratus 120
Damping B&K 750;Stratus 800
Weight: about same. Robust transformer power supply.
Drive load impedance: B&K 1 ohm; Stratus ?unknown. B&K can drive any load.

Subjective Listening:
B&K most tube like SS I have ever heard.

With the price so low the B&K is a remarkable bargain. However with e-mails and forum posts like this its price may rise?

No not new. Used from Ebay or Audiogon. About $600 maybe $700 for both. The older B&K units even sound better-look for blue stripes on front. They must be shipped carefully in seperate boxes about 50 pounds each. They are still fully supported by B&K and even upgradeable. They sound as sweet as tubes. My son just bought a pair on Audiogon for $700 with shipping. If you want e-mail me and I'll email you original literature, I have 3 B&K amps in the house.

The B&K Monoblock M200's are 150 amps peak to peak. You can weld with them. I run 4 pairs of speakers at once for my front channels. They can carry any load. I believe the best bargain out there.

Oh my gosh. The Denon is to the B&K monoblocks like a Cavalier to a Corvette. I use a Denon AVR 4800 for movies its good but it doesn't make music it just makes sounds. To make music you need the magical sweetness and unknown harmonics of a tubed preamp wired to a SS amp with unlimited power that can weld one quarter inch steel plates or drive speaker after speaker after speaker....

I apologize. I'm sure the 2000 is a distinct improvement. But I don't think it has the overwhelming power to easily drive those speakers without any strain at all. For example, the Denon can't drop below a speaker load of 4 ohms and would prefer 8 ohms. The automatic cutoff would kick in. The B&K's can drive below 1 ohm that's high current capability. I use it to drive 4 pairs of speakers simultaneously stacked to the ceiling -4 tweeters and 8 -6 inch midrange woofers on each side- a wall of sound. The impedance to the amplifier is below 1 ohm and would short most amps.
