IMHO and as stated on the title of this thread, IMHO the L10 and M10 are the best newly launched SS amps for the past 5 years, till June 2021.
(I can't predict the future
)
What really impressed me are their
Naturalness &
Realness.
They have more of everything than CH's previous amps and possibly ss amps of every other brands …. beauty, timbre, density, details/resolution, macro-dynamics and micro-dynamics, ambience and acoustic information ... etc.
The list goes on & on.
They are extremely immersive & involving.
I soon forgot my initial aim of evaluating them but simply enjoyed the music during all 3 visits.
They are quite like my MSB Select combo in characters.
Between L10 and M10, the former must be the invincible brother.
I guess there isn't any poweramp which is unsuitable to pair with L10.
For the M10, the speakers used and the listening room size are the two confounding factors.
I think one stereo M10 betters a pair of M1.1 monos easily.
If the room is large and the speaker very power-hungry, bi-amping (such as by a pair of A1.5 + a pair of M1.1) will have advantage over a stereo M10.
Of course CH Precision offers an upgrade path of Mono L10 and Mono M10.
But the price will then be astronomical! haha
