I have a pair of asp1000 monoblocks boards on the way with built-in power supplies. After reading the owner's manual, I am overwhelmed. It seems shielding, Twisted wires, extra aluminum plates for shielding, and even placement on how you turn or physically set the amplifier is hyper-critical about picking up noise. I originally planned to just drop these in a custom-made exotic wood enclosure and place them right behind the speakers. I'm now wondering if that's not possible. The little Sure / Wondom amplifiers don't even need an enclosure. Are these icepower amplifiers that terribly critical? Is it worth the effort, Wendy sure amps are basically plug-and-play play?
The owner's manual even has plans for building a specially shielded box to put your amp in. These seem like microphones than amplifiers. Can anyone verify if they are difficult to build without noise?
In my experience they are not picky at all. I have mine stuffed into quite tight alu boxes for a pair of mono blocks. 2 other friends have had them lying open on the floor. Dead silent. No problems at all. Sound was great.
I think that if you want to see those 117 dB of clinical SNR you might have to go to some length to achieve that.
So just fire them up - nothing to worry about at all. I have had mine for a long time (>10 years?) and so have my friends - no problems. And they take some punishment - I have shorted them and taking a lot of power out of them - no active cooling, just screwed to the box.
Have fun!

I did actually use RF suppressing ferrite on the mains inlets which sometimes are incorporated in the mains cables for e.g, a printer etc. like a snake that just had a meal - they fit into the box so - why not. My friends used them without I think. But a choke is an inductor right - thats something else... not used.
Be aware of that they are a bit lower impedance (8k) that usual power amps so you need proper driving to get the best out of them.

I can I need some advice on the best way to go about getting volume control for these asp1000 amplifiers. I've read about the high input impedance. I use a computer for my source playing Flac, wav or hi-res audio files. I'm using a very simple dongle Style USB DAC that sounds okay. I have choices, but do not know what my best bet is. For Simplicity, it would seem I should just buy a better desktop DAC, such as and smsl M500 and use the volume control knob on front. Or any other DAC with a volume control for that matter. I know I can use my volume control the USB. Provides through the keyboard on my computer. But with amplifiers this powerful oh, I figure I should have a volume control to prevent issues. My second option would be to purchase a regular preamp. This would be the most expensive option, as I would something at least as good as the Schitt Freya +, and that is $900! I would still need a decent DAC upgrade. The last way I could go, is something like an all tube gain stage. I would still need a DAC, but a simple gain stage kit should only be a few hundred at most. The other two options I can think of, would be the pass B1 buffer clone kit preamp for 150 dollars, but I don't know if it would play nice with a high input impedance of the icepower amp. The most simple and cheapest route, would be be sure digital volume control option. But I do not know how high fidelity that would be. I could really use some help. I've been out of this Hobby for about 10 years now. I feel a bit lost and appreciate everyone who has helped so far.
The issues I spoke of in the above post about using the computer for my volume control, is occasionally I would get a full volume blast of noise when doing this the last time I did this. With this much power, I could kiss some of these Accuton ceramic drivers bye-bye!
