Nicely summarised. Is the Penon Space providing a decent dynamics? Do you totally recommend it?
Two things which I totally agree.
1. SR8 somehow does not go well with other cables. Tried some high end cables (PWAudio 1950s with shield and FTS) but not much improvement. I should have paired it with a good silver cable to see the difference but there were none. I assume the default cable is one of the best options.
2. SR8 somehow doesn’t respond much to EQ. I spent quite some time doing EQ, increasing the mid-bass a bit but didn’t help much. The default signature is so good that it’s just unnecessary to go for any eq.
Thanks for the info. Let me add some of my points into this:
1. Cables - I have not tried many but the stock cable is definitely great one. It has been longer since I directly compared them so I did this again just now. The Space cable is definitely an improvement. It adds more weight to the sound, it all sounds fuller and wider. There is an improvement in bass region for sure. Overall sound is just higher quality. I don't like testing too many cables as I am worried about the socket's durability. The Space definitely stays on SR8. Might test some more expensive cables on them but that will be in near future. My SoundRhyme cable ended up on the KZ ZS10 Pro and it made a nice improvement on them, using those for travel.
2. Note sure, what EQ tool are you using? Is it on the dap, mobile or desktop setup? I am using APO Equalizer with Peace interface addon. It can definitely alter any headphones, any frequencies with ease. In terms of bass using the Space cable and minimum EQ settings the bass is more than enough for me. Strangely enough for full BA set these have fantastic bass texture and that is something I really like as that's the reason why D7200 are my default cans. I do like great mid-bass too but as you can see on my EQ settings bellow in that region I am not adding anything as I feel its just right in there.
But also to improve the bass... not sure what tips are you using but try to experiment with those. I use foam tips on everything, i like their isolation and comfort.
Once you have the tips sorted then make sure you are using high quality recordings and I forgot to say before SR8 are highly dependent on record's quality. If you play something old school like or in lower resolution then SR8 sounds very ordinary. On the other side play some audiophile recordings in lossless quality and they will totally amaze and bring a lot of emotions.
I assume that you have tried different switch settings, I ended up using 1-1, they sound the best to my ears.
