It was a PITA with mine as they were soldered in. If you have an older version with socketed opamps, then it's easy.

Video review is up.

Nice review. I just shared it in my FB.

Is it still the case that all Audio-GD products with remote controls only do a single volume step per button press on the remote, or have they changed it so that you can press and hold the volume buttons on the remote and it continues to step the volume on the device?

I've been considering getting one, but having to press the volume buttons a ton of times to adjust the volume more than a few clicks, sounds terribly annoying...

They haven't changed the remote. You're right, it's a PITA!

I usually set it to a desired volume by hand, and then use the remote to fine tune.

Said the heck with it and got the Master 9 instead. I thought the Abyss had good bass now I know they do man does this amp drive them the best I’ve heard so far. Not as warm as the Liquid Carbon but still not bright at all.

I'm considering between HE-9 and Master-9 + Power Conditioner. After reading this forum, it seems that the latter would be better choice because I could also use power conditioner with DAC , AV Receiver, and etc. However, the question is which power conditioner is suitable. My budget is around 1000 USD. Currently, Audioquest Niagara 1000/1200 is a choice. If possible, please recommend power conditioner you think it's good for my budget . Thank you for your help.

A good Power Conditioner/Power regenerator can be great and make your audio system sound clearly better. This is especially noteworthy the more your mains power is polluted. The problem is that not all the noise on the mains are the same and therefore we don’t have only one type of Power Conditioner or Power regenerators that is best to fix all mains problems. In my experience, many of the cheaper Power Conditioners, have as much negative impact on SQ as they have positive and the negative effects are often more notable on amps.

I have read most that have been written about Master 9 and HE9, and all seems to find HE9 to have a bit better SQ than Master 9. I would test Audioquest Niagara etc at home first. If it sounds good with your gear and mains power it’s a good buy because our digital gear is even more sensitive to mains noise than our analogue gear. If the Power Conditioner doesn’t sound better, than without, the HE9 is most likely a good solution that also can be used together with a better Power Conditioner later on so that the Power Conditioner clean all the digital gear upstream of the amp.

My setup is in my bedroom ( 3 metres x 4 metres ). My concern is heat creating by either Master-9 or HE-9, especially HE-9 if I run it on overnight. Will it heat up my bedroom temperature? Thank you for your advice.

The M9/HE9 will heat up your bedroom temperature a bit, yes. I turn my M9 off then not using it. No need to have it on during the night. It take like 1 hour until it has the right temperature during the summer and 2 hour in the winter for me in Sweden.

Thank you for your comment. I forgot to mention that I normally run my R-28 overnight for burning-in my headphone with Pink noise from Spotify. I concern that if I upgrade the amp to Master 9 or HE-9, either one will heat up my room, especially HE-9 when I burn-in them overnight.

Does the Master 9 drive Abyss 1266 with authority ?

 

[DarKu]

With all due respect, I don't think Master-9 could be described as having authority, or "cojones", or slam, whatever you are calling it.
It is a bit mellow, with slower transients.
It was not the greatest pairing with LCD-4 and I presume with AB-1266 it will be the same...

 

[marcan]

Damn I don't know what you have as an amp, but I have the he9 (which isn't that far from the M9) and I would describe it as precise, open and having authority...

I find the Master 9 doesn’t have as much slam as my other amp the Violectric V281 (both being attached to the same DAC)

Between Violectric V281 and Master 9 which one is more transparent and have better details retrieval ?
