I have recently made a post where I have asked if I am deaf or there is some system problem. So it appeared to be custom DAC having some issue. As I mentioned I couldn't get rid of the feeling to make every song louder to hear that juice but because of the overall loudness I couldn't listen for long.
So the creator of that DAC recommended me to try to listen to an AK chip, saying that it just a matter of personal preference. So I ordered Topping E30 based on AK.
I always thought that I am the one that can't distinguish one DAC from another so it doesn't really matter which one to buy. I haven't ever compared DACs before and reading all these forums saying - 90% of audiophiles exaggerate the sound difference they can hear - I thought I am one of them so I should just buy whatever is on sale.
But these 2 DACs are like different worlds. I have never been so wrong about myself ;D. Custom DAC is crystal clear, so reference so airy such a wide stage. But I couldn't listen to a single rock album using it. It wasn't fast enough to follow the song and that issue described before was killing me. However contemporary classic was perfect, that sound issue not so noticeable.
Topping E30 - everything is fine here with this issue, it's balanced and it's fast and lively ( for some reason too many people wrote in forums that ESS is lively and AK is clear but for me it is upside down and it is definitely not something that I imagine. ). I'm listening to rock music as well as to classic music and I am quite happy . But where are all those details? Where is that stage?
I am absolutely sure that I do not deceive myself on what I hear. Sound difference is huge. It's enormous.
My question is, if I do not have a budget of an audiophile - what should I buy to ge the best from both worlds?
Updated: Drop HD 6XX -> drop thx aaa one ( no balanced inputs ) -> mogami RCA cables -> custom made DAC based on ES9038Q2M chip with amanero USB input and bluetooth module -> klotz usb cable -> Anker hub -> MacBook Pro 16 11.4 iOS -> AppleMusic
My findings with the E30 are the complete opposite. I think this could be the sleeper DAC of 2021/22. It completely destroys my Logitech Transporter ($2000 original price tag). I can even handicap the E30 and play it with slightly lower volume, and it sounds better. The E30 has plenty of detail (more so than the Transporter) and what I didn't expect is it also has a nice dose of warmth to it. This is where other DAC's I have pitted against the Transporter failed. They were too (and I know this word gets used a lot and I tire of it myself sometimes) analytical (or too detail oriented).
And it's funny you mention the soundstage not being as wide because it's wider on my E30 than the Transporter. I have a high end switcher which I use to blind compare DAC's at the same time but the differences between these two DAC's were so great I didn't even need it this time around, because the wider soundstage was a dead give away that I was listening to the E30.
Anyway, I'm going to tell you straight up why you "couldn't get rid of the feeling to make every song louder to hear".
It's your HD6XX headphones. They lack a considerable amount of detail and have recessed vocals. So they give you this need to want to turn the volume up higher and higher until your ears get fatigued.
I suggest you try a different pair of headphones (maybe start with the HD600) OR try your 650's without the inner 'disc' pads.
