Need Amp Advice from the Collective

I will offer different advice.  Upgrade your LRS to a bigger model.  Even the 1.7i will be a huge upgrade, more than you will get from an amp upgrade.  I believe the 3.7 is the sweet spot in the Maggie lineup.

@billstevenson  @avanti1960  I used too be a proponent of class D. I have owned a number of newer class D amps (AGD, Jeff Rowland, Orchard Audio, Atmasphere, and a few others), and they do indeed have their charms. But what none of them has been able to deliver is the kind of sonics and imaging (high current?) of class A or high bias A/A-B amps. I am intrigued by the Rogue hybrid amps (I had their RP-7 pre and enjoyed it), and would like to try them. But again, I have never met a D that could deliver the kind of goods that these seem to need. I wish there was a lending library for audiophile hardware. 

@signaforce @easystreamer I assume the Simaudio is an A-B design? I also have a pair of KEF Ref 1's and they seem to have the same high current needs as the Maggies, so good advice. And the Accuphase is worth looking into too. Speakers? Thanks.

@celtic66 Yes, Sugden is intriguing. I wish, but I am afraid ~30 watts is just not enough unless it switches to lots of A-B when it starts to run out of steam. The Pass XA25 is similar. Wish I could get away with something that low wattage. What speakers are you using with the Sugden?

@kofibaffour Afraid we will have to disagree on virtually every point you made. And yes, I do have a subwoofer. 

I second boxcarmans advice. You have a nice sized room that will let them show/display what that speaker (3.7) can do.  You will need power but the Bryston  might do the trick with that speaker too

@boxcarman  @dgibans  I did have the 1.7s here on a trial and they sounded wonderful. But the physical size! They dominate the room! This is my living room, not a dedicated listening room. And the area where I do listen is fairly small - I'm about 9 feet from the speakers. The Bryston would drive them, no doubt. It has plenty of power and grip on the speakers. But it is too clinical for my taste. I can see why Bryston is used in studios. 

many who have dual purpose rooms housing their system usually deal with serious considerations that take precedence over optimizing sound quality at the listening position...  life is all about managing tradeoffs
