Thanks! This is really interesting. It must be really good if you prefer it over the D8000 Pro.I had an audition for about an hour yesterday. I brought my D8000 Pro with me for a quick comparison to the YH-5000SE.
The chain used: SP3000T (hires source) to DAVE (dac) to HA-300mk2 (amp)
At the beginning I listened to YH-5000SE connected to DAVE's 6.3mm headphone output. The sound was good but I was not impressed tbh. I noticed that while YH-5000SE is easy to drive, the bass was muffled and not controlled well. Then we turned on the HA-300mk2 and gave it some time to warm up.
The bass after having the dedicated amp is much better and the sound opened up. I tried the low gain and mid gain setting on HA-300mk2 and liked the mid gain better as it has more punch.
Sound-wise I think YH-5000SE is similar to D8000 Pro but they are not the same. YH-5000SE is a little bit brighter, soundstage a bit bigger, and also a bit more clarity (especially the piano). I think it makes sense since D8000 Pro was released 3 years ago.
I was on the fence if I should get the D8000 Pro Limited Edition. After the audition I placed an order for a pair of YH-5000SE immediately. The store owner told me that they have received many orders and my pair might come in next Apr or May.
What about the bass?
