I received a pair of HiFiMAN RE400i earbuds ($79) recently, to use with my iPad when I watch movies. The first thing I noticed was that the sound was very clear and detailed, with no harshness, even with the volume up...

The Benchmark DAC2 DX is a product of yore (in hifi time), yet has kept up with the competition in every way, all at a price at the low end of the audiophile scale...
Some readers have a dedicated audio or home theater room that just contains the electronic components and a few seats. Nothing to get in the way of the sound.
Heat is the main enemy of consumer electronics. Unfortunately, many amplifiers get hot during use, especially if they have any bias into Class A operation. I have several amplifiers that get quite hot
If you are like many home theater enthusiasts, you probably have your high definition display, either a flat panel or projector, some distance from your equipment rack. And, like most, you use an inexpensive HDMI cable.

You can imagine the results.
