It's been a long time I haven't been to my local Jaben. Turns out they had something extremely interesting and also, very obscure.
It's the Bakoon Products HDA-5210mk3 (Japan model only) and it's scarily powerful.
Paired up with my HE-500 and the synergy is unbelievable. At the low current setting, it is sufficient on powering the HE-500 but flick the switch to the high position and suddenly, everything is just a feast of power. The volume knob goes to 10 and it only needs to go to 2-2.5 to fully spread the HE-500's wings. This amp is so powerful that it makes the HE-6 look like it only needs milliwatts of power.
Problem with this amp is that I've been having trouble finding the spec sheets and the price (they told me it's more than $2000).
Also during my time at Jaben, I did once reviewed a bit negatively on the Ocharaku Flat-4 saying that it was like spikes of treble. Turns out I used the wrong tips (it was silicone tips that over-emphasised the treble).
I have reauditioned it with foam tips and my god, it is a wonderful IEM, Almost like a baby FitEar 334 but for a much lower price. One criticism though is the weird fit but that's just nitpicking. Sorry MuppetFace, you were right it's excellent.
Also reauditioned the FAD Muramasa. Excellent instrument separation but very midrange centric. The sound is also unique in its own way.
sexy amp. Is that an ALO cable, or one done by BTG?
that's the sweetspot :0 well for leather at least
