Look up the model of the keyboard they were using. Then get that keyboard.

lol

Selling repairable things with readily available parts is anti consumer? Someone tell John Deere and Apple that they’re failing hard! /S

Fun fact: drivers will perform poorer in higher altitudes due to thinner air.

You underestimate the Delta Airlines complimentary headphones.

Don’t quantify it. That’s about as useful as quantifying how a hamburger tastes.

Be sure to rest your ears too. Give them a break from loud noises for a week or two and see how things are.

Might be good to get a hearing test too to see if there’s any issues and establish a baseline.

Welcome back!

Stop listening to stuff. Go see a doctor.

Basically rehashing what others have said: sound quality is meh, catalog is good, it’s cheap, but software sucks.

Qobuz sounds better but catalog sucks. Tidal sound quality is kind of all over the place IME but catalog is good.

Using Amazon until subscription runs out, then will consider moving to Qobuz.

Topping keeps making bad amps: L30, A90, and now A90D.

Just buy a French audiophile wig.

the 6XX on Tubes (specifically OTL) is definitely endgame in my experience.

IMO 6x0’s are very amp dependent. Also thought they were somewhat “meh” for a while until I started going through more and more source gear and finding some great pairings.

I think a lot of people get a little disappointed when they hear the 6x0’s. I was one of them until I started going through more source gear and finding some of them really make the 6x0’s sing.

That said, all of the source gear that I really liked to pair with the 6x0’s costs at least as much as the headphones, if not many, many times more.

Neither. Rebecca Black’s Friday is the best burn in music.

Interesting take from your professor. Thanks for sharing!

I’ve also not gone too deep into the cable game but have noticed differences between them. However I seldom find a cable to be categorically better.

I’ve wondered about impedance and capacitance of cables affecting sound quality, but the single crystal note was interesting. I’ve generally ignored that as far as marketing materials go.

That said, I have come across a couple of cables that sound noticeably smoother than cheap cables, wherein the cheaper/generic ones tend to almost sound grainy in comparison. I wonder if the crystal thing has anything to do with that.

IME the 6x0’s do exceptionally well on the right source gear. If you’re planning on upgrading anyway for the Sundaras, it might be worth holding on to until then to try on the new source gear.

That said, I can’t think of any amps that paired nicely with it that isn’t just as much if not more than the cost of a 6xx. I haven’t tried 6x0’s on too many things but the least expensive one I really liked was on the Jot 2’s balanced out.

Stop tempting me!

LD -600?

I’ve experienced something similar at times. May just be crappy USB ports that’s leaking more noise than it should? Dunno.

Try turning on airplane mode, changing USB power settings, overall power settings to performance mode (or power saver mode?), etc. That’s after you make sure no other effects are being applied (e.g., make sure you’re in exclusive mode and some have said that the “disable all enhancements” setting makes a difference even in exclusive mode).

Try comparing to your phone?

IME yes. HD6x0’s in particular can do some interesting things with certain amps.
