Bought a pair of Magnepan LRS. Should I buy a Schiit Vidar or Bryston 3B-ST?

I own a pair of Magnepan 1.7 speakers. I started out using a pair of Schiit Vidars as monoblocks. For the most part they were fine. If you play classical or jazz at reasonable volumes you should be ok, and mine were ok. But if you play loud rock or fusion jazz you will not have enough headroom and one of my Vidars went into thermoprotection will playing Jeff Beck fusion loud. I sold the Vidars and got a pair of Bryston 4B3s. They are the ticket. Plenty of clean power. No protection issues. Plenty of headroom. Not sure about the 3B3s. But you can find the Bryston 4B3 on the used market frequently at much reduced below MSRP. I would still be using my 4B3s if it not for the amazing deal I got a while ago on a pair of 28B3s. Needless to say, I am set power amp-wise. I’m done. Bottomline: if you want headroom go with Bryston. If you are never going to play your system loud get a pair of Vidars (not one). 

Correction: My Maggies are 1.7i. 

Bryston all day long.  It will deliver the power needed for Magnepans.

Several responses. 1.  Bryston has been around many years and their amps are known for their rugged build quality, reliability and ability to deliver high current to current hungry speakers. Back in the day, some folks felt they did not sound as good in the highs and upper mids as some "others" that were much more expensive. They sounded great to me with good dynamics. 2.  Regarding bridging: a bridged amp will see a 2 ohm load driving a "4 ohm"speaker.  Remember a speaker is a reactive load and the real world impedance is all over the place when playing
 music. Most bridged amps are rated at 8 ohms so this makes for potential problems.  You miight ask: Is the amp in question 2 ohm stable?   3. I would not consider any speaker that takes 250 + watts+....and tons of current to play as loud as I want. Why would you consider a Maggie for ear injuring volumn levels?  Playing loud is not it's forte! (Ha!)  You can drive any number of horn loaded designs to 112 db or more with a good 100 watt amp. This is better than driving a power hungry speaker to its limits and the limits of the power amp. Hope you have a big space. 4. I had Maggie's for years and had no problem driving them with high current amps that delivered "100 watts" at 8 ohms and double that into a  "nominal 4 ohm" speakers. One amp, an ARC D-52, played both Dalquests (pretty power hungry!) and Maggies to uncomfortably loud levels.  5. I have dynamic speakers  in my main room now because of placement issues as well as available power. Good luck! ENJOY THE MUSIC!

Emotiva XPA2 on my 1.7i sounds great. Can one used for the same price as Vidars. I highly recommend.
