KEF LS50 Meta

The LS50 is a very good standmount speaker, and many people enjoy them. I have the powered version, LS50W2, and upgraded from the LS50W1, the original. For listening to the widest variety of music, pairing them with a subwoofer is recommended (the mid-woofer is only about 5 in, so the low end is limited.) I have used the REL T7i which does very well in that combination. (And I can recommend their Arrow wireless connector for use with your amp. Having used Peachtree integrated amps six years now, you should get excellent performance from the combination. I have not used that NAD amp, but I imagine it would do fine also.

The LS50’ and the LS50 Metas are great speakers and your amps will drive them without issue. Like any speaker, you will need to fiddle with placement and unless you are using them as near field, you will probably want an subwoofer to go with them.

All the best.

I have a set of LS50 Metas that I was using in my main listening room with a KEF KC62 sub. Nice sound and a great match with a crossover between the two at 90Hz. Amazing imaging with very good detail. Given the size of my room they were a little small sounding especially at higher volumes. I ended up replacing them with a open baffle speaker that completely fills up the space. I have since moved them into my office which is 10x12 and listen to them semi nearfield at about 5ft from my chair. From there they are magic. They still disappear sonically and also manage to fill my small room very well. Highly recommended for a smaller room. 

I think the KEF LS50 Metas are terrific near field speakers. Very, very capable.

I did an A-B test with the LS50 Metas and the Raven Audio Corvus Monitors (full review here). While the much more expensive Corvus Monitors won in the end, the LS50 Metas held their own very well and were QUITE impressive (especially considering their cost). I would highly recommend for small to medium size rooms. 

Good Luck!
