Trying Magnepans, need advice

I ran MMGs for a while in a room that size with excellent results. It sounds like you have a dedicated room which is key and actually gives you better options than a larger shared space.

I would (did) run them in the nearfield with a sub well away from the room boundaries. You will get a wide an craaaazy deep soundstage with good imaging and tone. Plus nearfield will take your almost square (bad) room mostly out of the equation. I am thinking speakers 3-4 for apart and you the same distance away. Keep speakers pulled well into the room.

I think you would be in for a real treat.

Nearfield Magnepans is where its at. An incredible sound.

I am about to take delivery on a pair of Magnepan 0.7s. I had been using SETs with the 45 which is not powerful enough for their 86 db sensitivity so I rebuilt my amplifiers to let the 45s drive the grids, through an innerstage step-down transformer, of the 833-As which take only 1kV through a Hammond 1642SE transformer which has speaker outputs for 4 Ohms.
When I auditioned the 0.7s they sounded more beautiful and clear than any $50,000+ speakers I ever heard when the store selling Magnepans held a public demonstration and seminar. I live in a small house 26 feet in diameter but the Magnepans will have more than 7 feet space behind them.

I used 1.7i with a sub in a room 11-5 x 15 and the sound was totally amazing. Most listeners seemed to prefer the sound without resistors. The room had plenty of lp storage , curtains and carpeting which tamed the high end.
