Rogue versus Peachtree

you are definitley looking at some great gear. for your info i have modified mmgs in a similar sized room as yours with a decco as a pre and a emotiva xpa-2 [500 watts per into 4ohms] many magnepan owners will tell you that you will never regret lots of power..i am into budget gear at this time so i have not listened to the gear you mentioned. the inova only has 80 watts into 6ohms so not much difference in the power dept from what you have in the rega. the grand integrated looks great as do the other amps. at that dollar amount you have many options though. IF, you have room for one more component and a small footprint dac like the hrt or music fidelity possibly ask your local dealer if he has a demo amp you could use for a few nights to see how a good quality, high current amp would work with your rega as a preamp? enjoy the shopping process as you have a great set of speakers and will have many hours of enjoyment ahead of you.

You might want to look at the Wyred 4 Sound integrateds. I am looking at the mINT right now - it has 100 wpc, with built in DAC. It is suppose to be on par with the peachtree gear. They also have a 250 and 500 wpc integrated.

Those Emotivas and W4Ss are also ones I've considered. I'll have another look. I like Hotmailjbc's suggestion of demoing a powerful power amp to see if the extra juice is really worth the upgrade.

I'd eliminate the Peachtree Inova in that I doubt the amp has enough ooomph to make the Maggies sing at their best.

I am a Maggie and Peachtree Grand owner, so I figured I'd chime in with my setup. I have both Magnepan MMG's and 3.6R's in a HT setup with the Peachtree Grand Pre used 95% of the time for 2-channel listening and used in HT bypass mode for a little bit of BluRay playback or Netflix streaming. You didn't mention anything about HT use, but the Pre offers a few nice features in that regard (bypass and fixed-pre-outs).

I initially listened to Peachtree products by demoing a Nova with some 1.7s, and I was instantly hooked on both the tube-buffered Peachtree and bigger Maggies, leading to my 3.6 acquisition. The Nova was able to handle the 1.7s up to reasonable volumes, but it didn't have nearly the clarity and resolution of a separate high-current power amp feeding my 3.6s (and I don't think this is due solely to the 3.6s)

I just recently opted for the Grand Pre, because I finally realized just how much the Maggie's love tons of clean power, and I didn't want to be tied to a specific amp, especially when the Pre sounds so amazing. I've been through a few amps with the Maggies and finally settled on a Bryston 4BSST2. If you really want your Maggies to sing, I'd recommend a dedicated power amp. I can play so much louder with so much more detail without blowing my Maggie fuses than with any of the lesser amps I tried. I was worried that the integrated might fall into that 'lesser amp' category. Though you aren't playing loud most of the time with a toddler, a big clean powerful amp will be magical with the Maggies. And you can pick up a used Bryston with 15 years of warranty left for not much more than the price difference between Pre and Integrated.

But as for your list of 4 options, the Peachtree Grand will produce amazing results with the Maggies if they're fed enough power.

Also, I am doing something very similar with streaming via Airplay and Optical input on the Grand. I often use my Macbook Pro and iPhones to stream to an AppleTV I purchased solely for music streaming. When connected to the Grand via optical, the CD-ripped digital music played through the Apple TV produced the best digital streamed quality I have yet heard vs. playing the same CDs through my Primare CD31...A testament to both the Grand's DAC and analog implementation around it.
