When I purchased When I purchased my unit from a local dealer, I also had this same problem. I took my unit back to my dealer and replicated what I was hearing for them. They ordered new tubes for me which resolved my problem.

I try to isolate any potential cable issues. I was not aware of some of these issues. Thank you for your incite and response.

I am going to reach out to McIntosh to see if I can get replacement tubes as well. Thanks for the reply.

Thanks for the info. Hope it does settle down. This amp is amazing!

So I am using my new MHA200 with my Empyreans. They sound amazing. However, without being fed an audio signal I can hear what seems to be faint static or feedback. When playing music with quieter passages it is evident as well. Any one else experience this with this amp and their headphones...

What sources are you using to feed her?

Thanks so much.

Thanks. I would only use it as a headphone amp.

How is it as a headphone amp?

You will adore it!

I have had mine for almost two weeks now, and I would say connected to main power source serves mine very well. I have Meze Empyrean, AKG N5005, and Audeze LCD i4’s. They all sound better from mains than off battery.

If my memory serves me correctly I would have to agree with your assessment. Though the M17 does quite well, and wow the amp is top notch.

M I have demoed the Hugo 2 extensively when I started my quest. The Dac is excellent much better than my M15. My M17 blows the Hugo 2 away as a headphone amp though. Kind the best of both worlds really. Very solid dac performance and excellent amp performance all in one tidy package.

I have only had my unit a couple of days, but regardless I have not heard the crackling noise. From reading the other posts, it does seem to be a rather common issue.

Yes I will. My goal is to decide if the M17 by itself will satisfy me versus my M15 and a good desktop amplifier.

I will have mine today. Can’t wait to dive in with my Audeze LCD-i4’s and my Empyreans.

I agree. We must continue to encourage development of any and all devices that have potential to produce great sound.

Micron cards are Absolutely. Not something the average user should be doing.

It sure does. Might be exactly what I’m looking for!

I do not believe you are wrong.

Jj Thanks.
