>What is it about discrete Class A balanced amps that makes Aryas sound better?

Generally speaking....

Discrete amp topology: is generally more adept at passing spatial information in the music as compared to IC based amps - ie: HxWxD and positional information. They're also better with revealing trailing edges and minute nuances in music/vocals/instrumentation too. IC/THX-based amps tend to sound sort of unnatural, by not reveal spatial info as well as - especially soundstage depth - as well as "cut-off" trailing edges/nuances whose details make music sound much more natural and "real".

Class A bias/topology: Most amps are Class AB - meaning that one transistor may drive the " + " part of the musical waveform, while another may drive the " - " part of it. In between + and - , neither will be 100% accurate when they pass off the signal to the other. What this is called is "crossover distortion" - when there will be a distortion of the waveform as the signal goes from pos to neg and back again, and this is a major part of an amp's treble harshness. Class A amps don't have any crossover distortion whatsoever. They have their output transistors handle the whole waveform - they stay "always on" through the whole waveform up until the amp is turned off. As a result, they're smoother in the treble and midrange than most Class AB amps - unless the AB amps are biased deep into Class A. Another benefit of Class A "always on" operation, is that they pass along more current into the load (ie: the HP or speaker) - which accounts for their deeper, punchier, and more dynamic bass capabilities.

Balanced operation: Balanced amps simply offer more power for the same voltage. Plus, they'll be more resistant to noise across the board - as well as being resistant to EMI, RFI, and may also have better apparent stereo separation.

Sorry for the long post, but you can do some more reading on each italicized topic. I really couldn't make the connection that amps made any difference as long as they were powerful enough. That is, until I actually tried out several IC based amps and compared them with my cheaper discrete Class AB amps - then, the differences were really obvious. Then I found a used Class A amp for a reasonable price (Gustard H20), and I was floored - the bass was sooo deep, punchy, and dynamic - while the treble and mids were uber-natural and smooth. Of course it took me getting the revealing Arya before I even thought about trying out different amps. Hope this helps.....

You can load the HD with WMA lossless, but I don't think Windows 10/11 supports that codec anymore. I have a bunch that I converted from FLAC to WMA lossless back in Win8 days.

If your tws support ldac you will have to tell Android to use it. Each flavor has its own verbage for it. Some actually say ldac others say higher quality over connection. Look in the Bluetooth settings to select this. Android only though. I think Apple only supports aac.

In a vacuum, I would agree with you. The meme part came from how it was a sudden, very unexpected turn compared to everything else that had came before it. A large portion of comedy is subversion of expectations and boy did that comic subvert the expectations of historically funny, light hearted comics. So while it isn't the most funny thing to me, I can see how some people can find it funny.

Yea, the new Heretic model has protection - I have the Heresy sadly (easiest way to tell is the Heretic has the gain switch on the front, Heresy in the back). I believe it! I plugged a pair of earbuds in while I was trying to figure out if it was the Heresy or not and it got insanely hot in a short order. Had it been plugged in much longer they would have melted!

Thanks OP! Glad your ears are better, I didn’t read all the comments but did anyone recommend wearing earplugs at night to help your ears recover? Might be especially helpful if your house has a lot of background noise.

Needless to say, I won’t be buying a Schiit amp or certainly not used! There’s too many reports of this, meanwhile I can google “Atom amp dead or blown” and not get a single result. All that power is tempting but damn I don’t want to risk my cans or my ears.

Edit: I emailed Schiit and confirmed: they’ll only cover damage to other equipment for the original purchaser. So if you buy used Schiit you’ll be risking your other equipment.

You know he is talking about solid state to tubes right? The whole placebo thing is about most solid states being identical, its pretty accepted that tubes do change sound.
