Odyssey Stratos vs. Monarchy SM-70 PRo ?

Oh that's a tough one. Had the Monarchy 70s and listened to the Odyssey Stratos at a buddy's home. The Stratos sounds more rounded too me. The SM70s a little cleaner with a slight sweetness to them. The sound will be more depended on how each unit works with your speakers and the preamp used. From hearing both..I would probably give the nod to the Monarchys in transparency.Both are very pleasant to listen too.

The Stratos mono blocs in the "extreme configeration" take about 400 hours to really get broken in. I figured 300 hours would do just fine, but even at four hundred hours they still were opening up. There's a big difference in them between 200 hours and four hundred hours.
As for how they sound? That's easy! Very fast, and very smooth. Kinda like an Accuphase sound. These amps will shake the plaster with ease, and the build quality is to die for. No matter how hard they are driven they still never get hot, and usually just barely warm to the touch.
They image well (very), and are extremely open. Does reed instruments extremely well, and may have the best piano I've yet to hear from a S.S. amp. The trumpet is right where it should be, but of all these instruments it does the upright bass better than anything I've ever heard.
When I first got these mono blocs I hooked them up with a B&K tuner/preamp, and just played the 24/7 till they had about 300 hours on them. Later I tried them with a Conrad Johnson PV10 preamp, and was a very nice silky sound. Tghen I tried them out with a Sonograph. The PV10 was better sounding. Then I went on thru a battery of tubed and S.S. preamps till I finished out with a Quicksilver linestage.
Once again a very nice combo, but was doomed a little later when I came into a Candela. The candela made the Quicksilver into a door stop! I've never heard a better combo. Acoustic jazz just seems to grow on you. The sound stage is huge. Very deep & wide. Just seems to make everything sound better. My amp / preamp combo is a keeper around here

Not so tough, though I haven't heard the SM70,s. I have 2 Monarchy SE-160's, 2 Monarchy SE-100 Delux's and 1 Odyssey Extreme with the red board. The Extreme is taking the place of the SE-160's because, well, everything is ever so slightly better. The biggest difference noted are the crystal clear highs and powerful base. The Odyssey can handle speakers down to 1 or 1/2 ohm (can't quite remember), allowing them to drive any troublesome speaker I can think of. Everything I've listened to sounds effortless. Even driving my buddy's Kappa 9's which drop below 1 ohm and are known to be amp killers are perfectly tamed. Go with the Extreme version.
