Hello MA members,
I'm thinking about getting a NM24 since it's at such a good price for both tube/ss DAC and a line amp. But the only major drawback is it has only a manual volume control. Any NM24 owners have tried to replace the stock volume control with a remote controlled one? Any help/guidance would be appreciated.
Also I've heard that combining the NM24 with the AC regenerator would further improve the sound. How much of an improvement is it and can some one that has both share his opinion?
Many thanks,
Dan

Hi Dan,
A customer did it in Hawaii. He uses the Gold Point step volume made by somebody in Sunnyvale.
Below is his comments:
Dear Mr. Poon,
Thank you for your responses regarding my latest modifications to the NM24 DAC/Pre. I removed the four 1800 uF capacitors in parallel with cathode resistors to reduce gain to the preamp section, and replaced the four Wima output capacitors with 2.7 uF Mundorf Supreme capacitors. The absence of the 1800uf caps added another needed three clicks to the volume control to reach my normal "ideal" listening level, and the over all mod brought some noticeable improvements in soundstage, details, clarity, and well define bass. But what I really enjoy is how smooth, effortless and naturally my system now fills my living room with music.
I'm using the combo of NM24 with the DIP Upsampler and the DR-1 digital cable for over three years now with much satisfaction. My original intention was to use the NM24 as a DAC and adding a high-end preamp later on to my system. Over the years, I have made other modifications to the NM24, such as replacing the volume control with a Goldpoint 24 step-attenuator, upgrading to NOS tubes and HiFi fuse, adding Bybee filter to the power supply and the digital input. All these modifications brought the NM24 which is already a great DAC/Pre to a performance level that exceeded some of the much more expensive preamps I was looking to buy, but no longer have a need for one.
Thank you again for your great customer services and great products, and keeping this hobby fun.
Sincerely,
Nhan N.
