Go with CH Precision. What are your speakers and source components (turntable/phonostage, DAC, streamer/DAC, CD/SACD player)?
Which CH models and FM models are you considering? Be a little more specific.
When I was auditioning the Magico M6 speakers at the Magico's own facility in bay area they had the M6 hooked up with the CH Precision's flagship power amp & preamp (M1.1 Reference power amps & L1 dual monoural linestage preamp and the C1 mono DACs served as digital front end source component). They sounded spectacular together and I ended up purchasing the Magico M6 speakers from the nearest Magico dealer from its facility but didn't get the CH Precision gears but instead I went with the Naim Statement NAP S1 monoblock amps & Naim Statement NAC S1 linestage analog preamp, which are quite a step up from the CH Precision's flagship Reference amps & preamp but also cost quite a bit more than the CH Precision M1.1 Reference amps & the L1 dual monoural linestage preamp.
If you can afford the Naim Statement NAC S1 linestage analog preamp ($90k) and the matching Naim Statement NAP S1 monoblock amps ($180k) I would highly recommend them. But you better have really competent high quality front end source components (either digital or analog front end or both) to pair with these Naim Statement pre & amps combo, and as long as your speakers are up to the task and are justifiable or in the same league as these Naim Statement gears in order to achieve best overall end results. These Naim Statement gears are indeed truly special and sounding highly musical especially for listening to high end analog front end source components eg turntable/phonostage combo. I listen mostly to my Clearaudio Statement v2 turntable w/ a Statement TT-1 tonearm, a Statement Goldfinger cartridge, discrete class A linear PSU for the turntable & the D'Agostino Momentum phonostage pre.
Other products along the line of CH Precision that I highly recommend would be the following : Soulution, DarTZeel, Tidal, MBL, Burmeister, Chord Reference lines, Vitus Audio, Gryphon, D'Agostino Momentum M400 monoblock amps & Momentum linestage preamp or perhaps his latest flagship Relentless monoblock amps if you can afford them, Boulder, EMM Labs, Audio Research Reference series, Pass Labs' flagship models, VTL, VAC, BAT, Lamm, Ayon, Ypsilon.
