CH Precision L10 & M10 : My votes for the Best SS amps (for the past 5 yrs till 6-2021)

[CKKeung]

The flagship Series 10 of CH Precision was announced during the Munich Show in 2019.
A few engineering prototypes were displayed then and Florian claimed that they would be ready to launch by the end of 2019.

Delay seems to be inevitable for flagship series launch of every brands & CH Precision is no exception.
Compounded by the COVID pandemic in 2020, there has been further serious delay.

There have been some posts on WBF from the various dealers :

However many of the customers worldwide who had placed orders have not received the amps yet. The situation is the same in Hong Kong.
I am lucky and have visited the CH Precision Asia Office in Hong Kong 3 times to listen to these fabulous amps.
Let me share with you some photos.

The first visit in mid 2020 :
The HK office got the L10 only.





The L10 was accompanied by D1.1 ; C1.1 Mono : Stenheim A5 speaker ; bi-amped by a pair of A1.5 and a pair of M1.1 :




The second visit in late 2020 :
The M10 had arrived and was driven by the L10.




The frontend and speaker remained the same :



The third visit was 1 month ago:
Still L10 + M10
Speakers changed to an Avant-garde horn :




But this time there was a Goldmund Legend !



I would share my views on L10 & M10 on a following post.

 

[CKKeung]

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

Fantastic! Great feedback.

Have you heard the Robert Koda K160s? Have you spoken with anyone who has heard both, even if in different system?

Yes, I auditioned K15ex & K160, but in a diff system.

 

[LL21]

Very interesting! Any 'listening notes' on how you 'guestimate' they compare in terms of sound character? ie, one more neutral, one greater bass authority, etc?

I have just shared my views with you via pm.

 

[LL21]

Thank you!

Great thread! CH Precision doesn't get enough attention imo. In fact I was just starting my own thread about them - which I'll still do since it's a system thread and not focused on the new 10 series.

 

[ashandger]

Great idea Ian. Looking forward to hearing your thoughts. Many thanks

 

[Addicted to hifi]

Absolutely stunning amplifiers.

 

[MadFloyd]

@CKKeung I'm curious if you know whether you were listening to the L10 in local or global feedback mode?

 

[CKKeung]

@CKKeung I'm curious if you know whether you were listening to the L10 in local or global feedback mode?

Yes, I was demoed the diff settings of grounding/feedback and I considered one of them my favorite.
However I forget which is which now.

So you heard a difference with the grounding as well?

 

[CKKeung]

So you heard a difference with the grounding as well?

Yes.
The final preference gave a more open sound IMHO.
Not difficult to differentiate.

Hi Everyone. The L10 has a new feature for our preamps, the ability to select 0% global feedback or 100% global feedback. The L10 defaults to 0% but one can easily change this setting from the front panel or with our CH Precision control app. I prefer 0% in the listening I’ve done with L10 stereo and the L10 mono. The presentation seems to be more three dimensional and real with the 0% setting.

As far as grounding is concerned, we implemented the same design concept on the L10 as the L1. Rather than the jumper that was present on the L1 we now have a switch that ties signal ground to earth ground on the L10. In an all CH Precision system I recommend engaging the switch on the L10 (to connect signal ground to earth ground) or placing the L1 jumper in the black/yellow position. All other CH Precision components should be black/black or jumper removed (1-series) or switch open on M10s. In my system this provided the quietest background that let even more details in the recording come through.

HI Ralph

when u say you recommend to engage the switch on the back of the L10 wrt grounding - u mean push the switch to "Linked"?

HI Ralph

when u say you recommend to engage the switch on the back of the L10 wrt grounding - u mean push the switch to "Linked"?

Yes. "Linked". If using L10 mono, switch position should be "Linked" on both L10 units.
