We are pleased to announce that our C1 D/A controller has been certified Roon Ready, thanks to the new Ethernet Streaming HD board.

This new option board can be fitted in any C1 (and C1 mono) that is equipped with a Digital Input HD board. All I1 universal integrated amplifiers can also benefit from this upgrade.

Please note that these three products are also Roon Tested, thanks to the USB Audio Input option board.

New C1, C1 mono and I1 firmwares supporting this new board are freely available from our website.

As part of the A1.5's development, CH Precision has recently compared top of the line electrolytic power capacitors from several of the most renown component manufacturers.

Voltage rail ripple measurement, amplifier output noise measurement, and most importantly direct listening comparison allowed us to easily rank the tested models in term of micro and macro dynamics, noise floor and low frequency control.

After further refinement and customization with the manufacturer of the best model that we tested, we were able to finalize the A1's bigger brother, the A1.5.


CH Precision then built upon this knowledge and new partnership to co-design a 120'000uF capacitor to replace the M1's 100'000uF used so far.

The improvement that these new power capacitors provided was so striking that we decided to discontinue the original M1 model and replace it right away with an M1.1 model, featuring these custom-made red 120'000uF capacitors.

All original M1 owners can contact their local dealer to arrange an upgrade to M1.1.

If you'd like to know more about the sonic improvement that these new capacitors brought, please read Mr. Roy Gregory's report from last October on The Audio Beat.


Following its world premiere in Hong Kong this summer, and US presentations this fall, we are pleased to announce that the first production batch of A1.5 has left our assembly factory last week.

Contact your local dealer to arrange a demonstration of the new versatile CH power amplifier.
