Magnepan 1.7 to 3.7i or Pass Labs XA60.5 to X100.5

I'm in the process of upgrading my system and facing a choice. Currently I'm using an pass labs amplification (XONO, X1, XA60.5) feed by Michell Gyro, SME IV and Shelter 90x and ending with Maggie 1.7 (mye sound stands).

I've listened to both 3.7i and Wilson Sabrina, Sashas, all of which could benefit from a bit more amp.

I have a dedicated music room (12x10) and listen to late sixties classic rock, country rock, folk as well as Cash, Owen country and vocal jazz.

I have trade-up value for the 1.7 at my dealer as well trade-up value on the XA60.5. I could probably stretch to a demo pair XA160.5 but am concerned without a dedicated power outlet I'm taxing the system. Also by the way, I don't tend to push the system beyond a bit past midpoint on the pre-amp, although the XA60.5 class-A meter dances about on complex crescendos.

Two question. Upgrade amp or speakers first assuming only one change for the next 12 months? If the amp, is the XA100.5 enough of a jump?

18x15 is much larger and could handle the 3.7's.

Keep the 1.7s, keep your amplification. If you really want to energize the room, improve tonal balance, and have a rig that sounds right on any kind of music, spend your money on one or two (preferably sealed) subwoofers.

JL Audio now has the more affordable Dominion and e-Sub lines. e-Sub also has a high-pass network which could reduce strain and increase dynamics in the 1.7s. They have been enthusiastically reviewed by TAS. I have a pair of Mirage MM-8s which are pretty similar in performance to the JL Dominion d108s. I can't *believe* what good sound I get out of my rig. It really popped into focus when I got the phase control dialed in right.

Anything from solo instrument or voice up through acoustic ensemble to classic rock to brash big band to full scale orchestra and chorus or opera, it just plain delivers, and the subs take care of the bottom octave while letting the 1.7s shine from 45 Hz on up.

As for opening the door, the room does not have a door. The opening is essentially a double doorway.

Subs may be the way to go. Thanks again.

The Pass Labs XA60.5 should be fine driving the Magnepan 1.7. The Maggies are 4 ohm, the XA60.5 does not leave class A until around 120 watts. I would try one of the Magnepan bass panels. This can also make the speakers sound fuller.

I have a friend who has the 3.7i with 2 bass panels. He is driving them using a Pair of Pass 60.8 monoblocks. This is a very nice sounding setup.

Placement is very important with Magnepan speakers. I would get a setup disc that has a couple of mono tracks. This will help you check and fine tune their position.

I had the 1.7's and thought the bass was the best quality the speaker had. It was a quality over quantity issue. The only problem with that is that it makes it very difficult to integrate a sub. On top of that, your room is not that big. Will your dealer let you try a different amp, or even a sub?
