Maggie LRS amping question

As I posted above about a year ago, I was interested and subsequently purchased a pair of the LRS+s. They are used in a medium sized bedroom which I believe serves as a good 'fit' for them.

I am currently driving them with a Pass XA25 as many know is a high current 25wpc class A amplifier which runs closer to 80wpc in A/B mode.. If my room was any bigger I believe I would need greater power.  As is I do not push the volume much above 90dB peaks. playing jazz and pop rock. The sound I am getting is sublime.  I believe I would want a more powerful amplifier for harder rock or large symphony music at higher dBs. 

I feel the LSR+ to be an outstanding speaker demanding of refined sources and amplification belaying there cost. 

I look at the LRS as a gateway drug. If you start thinking that maybe you can get better sound, you'd better have the money. I quickly went from the LRS to the .7s to Spatial Audio Lab's X5s. That's a geometric progression money-wise and that doesn't include the amps which pushed the money envelop further. Maybe the best option is just to be happy where you are and do the little tweaks such as the magna-risers etc.

I will be happy with the LRS+ because my room will dictate that I do not get anything bigger. The LRS+ is not bad, I was hoping it would be as good as my RAAL SR1a earphones (read that in a review) but it is not. However, the LRS+ sounds excellent and I am extremely happy with it. I only have 100 hours on it so a lot more room for improvement.

I noticed the LRS+ is even good at low volume with my modded Peachtree GAN1 (200W at 8 and 4). Though I am limited to only 1 source and a crappy volume experience. Thus, I am looking for an amp to pair with one of my 2 preamps, the Benchmark LA4 or Holo Serene. The modded GAN1 will go for headphone duty.

I spoke with a sales guy at TMR Audio today and he said the Benchmark AHB2 is OK with the LRS+ but it lacks power when the speaker is driven harder. I was guessing that to be the case from my experience with the Thiel CS3.7 and the AHB2.

I am looking to get another amp that will work with both the LRS+ and my soon to arrive Yamaha NS5000 (on Friday). I narrowed it down to the KRELL Duo XD lineup. I owned the Duo 175XD and sold it, but it will be great on the LRS+, I was not sure about the NS5000, but after some online research I think it will also be great. The other amp is the CODA #16 which will be heard with the LRS+ this weekend.
