Does it fit properly on the MHA200? Mine is sticking out a little bit from the based.

Mine fits flush but the pins will be a very tight fit unless you give them a cleanup with a product like Deoxit. Makes a massive difference even if the pins look clean. Aside from a good clean contact the residue is a lubricant so the tubes will insert easily compared to untreated. Goes almost without saying, be very certain all the pins are lined up properly. If one isn't there is no way they will go all the way in and fit flush.

Thank You for Deoxit recommendation.

It’s a 125mA small slow blow fuse (no wonder they went C7 - this thing takes no juice at all).

Correction- there are 2 fuses in the unit. The aforementioned 125ma + another 1a slow blow.

Does anyone have a preferred power cord with their MHA200?

I've been using a self-reterminated Analysis Plus Pro Power Oval with Monosaudio connectors. Just tried the Audio Envy OE-Lite and wasn't a fan (very fast, but too light on the low end). I'd like to try something else OCC, perhaps the Wireworld Mini-Electra next?

Our customers seem to prefer the Tributaries and some a selecting the Nordost. We don’t have good responses on the AudioQuest. I haven’t auditioned any others yet. I use the Tributaries personally

I prefer..... what I have. Jason, what is it that I have?

I believe you have the AudioQuest. No ones offered up impressions on it yet. What’s your thoughts?

I peeked and I have the Isotek. It is a
lovely purple. I think Wayne recommended it as I have an Isotek power conditioner and cables for my other components.

Definitely a good suggestion from Wayne.

Reason?

Reason?

I realized I happen to be more of an OTL guy. Little less detailed and warmer sound. Call me crazy? lol

So I just found a fairly nice solution to my gripes regarding the overly sensitive volume knob on the MHA200:

Microsoft Surface Dial

This is a Bluetooth knob that can be programmed to do many things on any Windows 10 computer - including volume control. It has a nice heft and feel to it, and since it's wireless, can be placed very close at hand anywhere on your desk. The Surface Dial allows for very precise adjustment of master volume of my PC, and the sensitivity can be changed to suit your preferences.

I basically went "up one" on the load switch, set the MHA200 volume knob at unity, and now use the Surface Dial to control volume using my PC's windows master volume control - works like a charm. Truth is though, you could probably use the "ideal" load setting and just set the MHA200 volume to whatever sounds very loud (too loud?) to your ears when the windows volume is at 100% and get the same effect. I guess I like the idea of taking the volume pot out of the signal path.

Since the volume control is happening in the digital domain - it's hard to imagine this could cause any issues with sound quality - and to my ears there are none, but would appreciate any input on this. Exclusive Mode in Amazon Music still allows volume control in this manner with my setup.

I was thinking about getting a Schiit Freya S to use as a pre-amp, but the idea of adding another active component to the signal path isn't ideal, and not having the clutter of a big pre-amp on my desk made this seem like a better choice.

This obviously doesn't work for those folks who are using a transport/cd player/turntable as a source, but for the majority of us who use a PC it works great. There are cheap, Chinese made, wired volume controls available that do a similar thing, but without the build quality and programmability of the Surface Dial.

This honestly removes my only qualm about the MHA200. In fact, even if the MHA200's volume pot was perfect, with an ideal slow ramp, I'd prefer using the surface Dial.

Cheers.

Found it interesting that we are using almost an identical signal path (Bifrost 2--MHA200--LC2F) and have the same issue with the volume control.

I'm considering the Schiit Jotunheim 2 as my preamp. Same size as the Bifrost so no real difference on desk space used. Adds the ability to use a solid state amp if I ever felt the need. Not sure why I'd want to with the MHA200. Also only $399 if you don't get module.
