Got a somewhat respectable stack now consisting of the TC, gustard x26pro dac and burston GT amp and honestly I can't hear a difference compared to, let's say my phone.

The biggest change was the amp, and even that was really small. I ran a 3.5mm to dual RCA from my Asus monitor to my Burson GT and that seemed to change the way the bass sounded. More clean with a very slight boost in the deepest parts of the bass. Not a huge change, but that's one of the only things I noticed. The cleanliness of the bass.

Now do away with the monitor and in it's place we have the gustard DAC and really I don't hear much difference. Running the TC right out of the monitor sounds like 95% the same. I'll have more volume from the amp but it was already going deep and loud before from monitor's 3.5mm out. Guess I've hit my ceiling as a listener.

And with the TC changing its sound depending on temperature and how it sits on your head, being a glasses user I am, I find it really hard to pinpoint what part of the chain is responsible for what I hear.
Take some time to enjoy your new setup and don't stress too much about being able to hear a difference or not. If it's your first time getting a full desktop setup it may take some getting used to. I remember getting my first 5k tube amp and thinking it sounded exactly the same as my laptop output, just more power and didn't have to turn up the volume so much.

Spend a good week listening continuously, not A/B'ing the two setups every minute or something, then switch back to your phone, you may be surprised. For many instances with high end gear, I found the best way to appreciate and notice improvements is actually when it's taken away, not added.

Yeah. I'll get used to it. Then A-B in a week or two. Realizing what you don't have is a real thing for sure. Because when I put on my old HD560s I'm like "damn this thing sucks in almost every conceivable sense. No amount of electronics will "add" to what it wasn't doing.

I totally agree on your observation. I also listen to Susvara and 1266 from mid-fi amps as the difference to summit-fi amps is not audible for me. Especially not if blind tested. At least it's good for your wallet, if you know that :) But the 1266 itself sounds much better than all the other headphones :smile:

I mean, I will add that a lot of this stuff is mental as much as it is technical. Diminishing returns sure, but a lot of the time the perceived sound quality can be greatly reduced if I'm not in the mindset to actually enjoy the music I'm listening to.

There's a reason so much snake oil exists in this field, and it's because you can't really listen to music without feeling it. Being in the space to feel it comes and goes, sometimes without much cause. Sure, you can listen to the noises and figure out the difference in fidelity. But the noise has to become music for the magnitude of difference to become apparent.

Every pair of headphones, and every piece of equipment I've ever had either sounded "meh" or sounded great at some point.

Placebo, mental biases, mood and mindset are all playing a key role in music quality. I'm sure you probably know this already, but I figure I'd share my two cents on why you should give it some time. The best way to listen is not when you are thinking about how much money you've spent on it and how it should sound, haha

Yes absolutely, with my mind at ease knowing I have a pretty good system, I'm no longer searching or wondering "what does better sound like? How much will X improve if I add this in the system?" No more doubts or suspicions clouding over what should be a good session. Now that the system's here and I can listen easy knowing I have everything. That's where the enjoyment and appreciation came come in. I've seen a lot of people continually chase whatever new thing came out and never really sat back and listened to how good their system was already. Don't kid yourself, trust that it's already good.

I couldn't stack the GT on top. The bottom of it would become burning hot, so I increased airflow by propping it up with some foam I cut up from the Gustard packaging. It's ghetto, but the important part is that it keeps it cool, and costed nothing. I would need to buy longer XLRs and some sort of stand or rack, and that's on ice for awhile.

You might want to try using Mapleshade Isoblocks (multi-layer rubber-cork laminate) for 36.00. They should work well and make it look much better than the foam.

I agree that multi-layer rubber-cork-cork laminate can be effective and look much better than the foam he is using. However, if you're stacking components and using the rubber-cork-rubber isolation blocks, use cut out felt, mylar or something that won't stain your components on top and bottom of the blocks. I use a cork rubber devices under my Butcher Block Acoustics maple turntable plinth. When I moved my turntable to rearrange my components and happened to look at the underside of my maple plinth, I saw black stains where the rubber made contact with the maple wood. Since the stains are on the underside of my plinth, it's no big deal but I would be upset if the stains were on the top of my component. Just a word of caution about using Isoblocks, sorbathane or anything else that may leave stains.

Good to know. I would think on an aluminum housing or metal housing it should rub off easily. Wood is absorptive. I did not realize they did that.

Myrtle wood blocks might also work, but not absorptive. They will isolate and not leave a residue. Something else inexpensive to try.

Unfortunately the stains from rubber or sorbathane are not easily removed from aluminum or steel cases. I know from experience. It's not a big problem if you're aware of it. Just buy some felt pads from an arts and crafts store or Amazon and cut out the shape required. You can use a small piece of double sticky tape to keep the felt from moving around.

I've been using Herbie's https://herbiesaudiolab.com/ products for years without issues.

The FAQ states "Our silicone-based products do not ooze or leave a residue. They they do not stiffen and crack over the years like rubber or squish out of shape like some footers. They'll be just as good as new for a lifetime and longer."

I've used and reused them over and over with no issues. And, do read their FAQ.
