JBL Studio 590 Speaker Review

[Chrispy]

I fell for the more musical nonsense because I had two klipsch r12sw that sounded slow and flabby but were just "ok" for HT boom, and expected musical to be more accurate and fast and blend with music better.

It can't be worse than those, can it?

Hopefully a bit better than the Klipsch...no such thing as slow or fast in a sub, tho.

Ok so I think it's your setup with the headphone out or the amp was running out of power and going into clipping. The 8:30 Mission Impossible part is more dynamic and I could see that needing to draw more power than was available.
As for artifacts, it's like "hearing pixels" to me at low bitrates, graininess, and harshness. With that said I tested with my AT M50X + Topping E30 DAC + L30 Amp to remove the room from the equation and do a more critical listen. The track sounded pretty good honestly, but I think I hear a little bit of harshness, but I'd need a lossless track to verify if it's the recording or the compression. I think it's your setup though as it's not obvious.

Your REL sub is good, it's just the high MSRP and BS marketing that keeps me from recommending them. Getting one on discount would change that though. The R12SW on the other hand is not a "good" sub lol. So a big upgrade

Or the recorder got overloaded with the higher levels of audience applause was more my thought. Hard to know.

That was the other track with the lady and mic clipping like crazy, I was talking about the studio recording mix.

I switched to using my laptop headphone out (problem persists with youtube content) but then I found this site with some 320kbs mp3's.

TAS The Absolute Sound 1996 Album For Audiophiles - Audiophile Music

The Absolute Sound (TAS) is a collection of great Audiophile versions of the year. It includes songs from a variety of genres.

audiophilemusic.io

Almost every song on that site is much much better, not quite 100% but a noticeable difference in that subtle static sound and every other aspect of the sound is better than youtube.

Almost every song is better except for track 15 (Dias irae), that one sounds like garbage and it's hard for me to imagine that's on the recording they chose for an audiophile CD. Does track 15 sound static free to you?

15 sounds fine to me on headphones, no static.

I was just going with the youtube link/video, where the audience applause definitely took it to a different place, assumed it was poor monitoring of level more than anything. Why would you compare a live thing apparently recorded with a handheld phone to a studio mix?

That's weird. What are you using as a playback device? I'm using a windows 11 laptop and the audio on that track is really bad whether I send analog out of the laptop headphone connector directly or send hdmi out from the laptop to the tv and then use the tv's headphone out.

There must be something wrong with how the computer is converting these bitstreams?
That's the last thing I haven't changed out yet is the computer as the streaming device.

I think I found part of the problem, aside from the lower audio quality of compressed content.
Switched out the power supply I've used with every one of these amps with a new one I just received, problem solved, for the most part.

I still think there is something wrong with how my computer is handling track 15, but it's not like it was with the new power supply.

It's weird how it wasn't a constant background noise from that power supply but noise that varied with sound output.

Win 10 > USB > Topping E30 > RCA > L30 > AT M50X. If you have Windows at 100 it will have a higher noise floor due to Windows Audio Session API (WASAPI), have to use AISO to bypass it. Ya my old PC's PSU had ground loop issues that would effect all audio output that involved metal (3.5 and USB), even across two separate builds, so I had to use Optical out. Swapped PSUs and now it's fine.

Yea I'm not so sure what if any percentage of the problem was the power supply now.
I'll have to test more again when my ears are ringing less from tinnitus which has been bad recently.

It seemed 50% ? better with the new one then I went back to the old one just to verify, and by double blind testing myself by not knowing which plug I was actually plugging in each time, I can't reliably tell.

It's hard tracking a thing like this down when it's not all content revealing a problem and not so noticeable at lower volumes, plus when your hearing changes with respect to how much your ears are ringing from tinnitus at any one time.

Part of the problem is the low quality youtube content and hearing every compression artifact or defect, I'm pretty sure about that. I need a preamp specifically selected to smooth that out or something.

I think you just need to trust less trustworthy sources to start? Why waste so much time on unknown provenance? Gathering great recordings is far more satisfying than trying to elevate those that have issues.....

I will start to gather a collection of high quality music for sure now that I can hear how much it matters, but even still much of my time is spent watching random stuff of all kinds on youtube.

I watch very little tv or movie streaming any more, no MSM for news, almost all my news and entertainment and hobby channel stuff I'm following is on youtube, I couldn't avoid youtube if I wanted to. Even if I'm just watching news there I don't want it be shrill sounding, especially not when each commercial comes on and raises the volume on me.
