I would like to purchase a stereo integrated amp that has a small form factor and should connect with PC/Mac via USB or HDMI. The first amp that I found that fits all these requirements is NAD D7050. However, I have found mixed reviews for the 7050 so far. Some people even found it inferior to...

I'm repairing a Buttkicker BKA1000. It was dead/blowing fuses. I replaced 4 IRFP250N FETS on the the high side. Also 6-8 electrolytics on that same side. Now it lights up and turns on. No shorts. But...no sound. I believe I know where the problem is but I'm on a big verification kick (no more...

I recently bought the Wharfedale Titan 12D class D amp speaker. This is an active speaker. The problem is that when the speaker is turned on but not in use, it goes in to "sleep" mode. The speaker works fine when there is a constant sound signal being sent to it for example, listening to music...

Hi, I just wonder what the general opinion is on using Class AB vs D amplifiers in subwoofers? Generally, I know Class D amplifiers are more efficient than AB. So it should mean lower power consumption and less heat. But are there other aspects to consider apart from that? For example I read...

Hi, I just wonder if there are any high quality Class-D A/V Receivers on the market? I'm been looking some, but have not found much. Since A/V receivers are 5.1/7.1/9.1/... , there are a lot of amplifier channels. That means lots of heat, large transformers, and physically large A/V receiver...
