When I had my 200-watt Peachtree GAN1 unit on the LRS+, I thought it was excellent and a super bargain system. In the last couple of days using the 150-watt CODA #16 on the LRS+ sounds like a totally different speaker, way more bass.
I even put my RAAL SR1a and CA-1a phones on the CODA last night and I have never heard that much bass and detail from those phones. Moreso, than the amazing RAAL VM-1a headphone amp.
Whatever second amp I get for the LRS+ will have to have a lot of power. I need 1 more amp and a small form factor is a huge driver, as is high-power, I am thinking the CODA #8 v3 or the SPL s1200 (never heard this one). Just need to sell the VM-1a to buy the second amp.
