deciding betw. some fine, small speakers-Advice?

Hi—First post! Long-time reader--I have made numerous purchasing decisions using this forum. You will see I am something of a budget audiophile. I am having trouble deciding between these fine speakers: B&W CM5, Dynaudio X12, DALI Ikon 1 MK2 (or a used MK1). More exotic, but still of possible interest: Dali Royal Tower, and B&W CM1. I have a space constraint, hence these speakers (the Royal Towers are the largest, being the only floor standers--also the most beautiful form factor, IMHO). I am requesting advice on which speakers will go best with a tube amp (MP-2a3C by Dared, for example) and which would match best with a pair of Bryston 2b bridged to monoblocks. I use a very transparent PS Audi pre-amp (PS-4 with no line amplification--close to a pass-thru signal). My sources will be Marantz SACD 8005 mostly, but eventually I will have my largish Redbook CD collection ripped to FLAC playing via a local, wired server, possibly a Mac.

I listen to everything, except hip-hop and rap (yes, I sometimes listen to some techno and hypno, despite being 55). I have a penchant for classic rock, prog rock, blues, jazz, and classical/neoclassical music. I have decent ears (trained by Monster Cable engineers) and have had some of the high end of my ears shot off by 45 years of playing drums. Additionally, I like (for contradiction’s sake) tubey sounds—meaning I seriously dislike listening fatigue and harshness in highs and mids. There is no Monster Cable in my Gear--I have hunted it down and replaced it with newer, less costly cables all around (think along the lines of Blue Jeans Cable, factory terminated). OK, I'll admit I still have a couple interconnects.

Your thoughts on possible speaker choices and matches to my amps are welcome. Thanks and fine listening!

Welcome to the Audiogon forum!

When using an amp in bridged mono mode, the minimum speaker impedance is 8 ohms. Using lower than 8 ohms will risk damage to the amps. From the speakers you listed, the B&W's are the only ones that are 8 ohms, so the only ones you can use safely with the bridged Bryston's.

The MP-2a3C is an 8w SET, and none of the speakers listed are suitable for it. This amp needs speakers with a much higher sensitivity, something like Zu, Tekton, Klipsch, Omega, Coincident, Decware.
It just so happens that a pair of B&W DM5s just came up on the board at half off retail - I have no relationship with the seller.
Don't know how they pair with your amps, but a used pair of Nola Boxers or Joseph Audio RM7s exhibit many of the sonic characteristics you're looking for. Given your preferences I'm a little surprised you have those Bryston amps. Best of luck.
