Just gotten my unit of the K9 pro. My impressions is that it drives my HD800s really well. Prior to the K9, I was using the ZEN DAC & ZEN CAN stack. On that stack, I always turn on truebass thinking it's a necessity for open-back headphones to get more oomph. Interestingly, I need no EQ of sorts...

I noticed the balanced output on the back of the ZEN CAN, may i know what purpose is it built for? and does the volume rocker control the balanced output at the back? thanks.

Congrats. I have the Zen DAC and they are exceptional. Its an engineering marvel that it does not need external power supply, I hope more products in the market can do the same.

You can trust me on this, my head is small, and I have leakage on the front and back of my head. I listen mostly to pop songs and outdoors, I use the momentum true wireless (a bassy monster). The ifi zen dac's truebass function fills in the missing sub-bass of the HD800s nicely for me. I have...

I have the ifi zen dac, I use the analogue bass boost and find it complements the HD800s very well, you might want to try before giving up on this excellent pair of can.

You will need something like the iematch by ifi to decrease the sensitivity. On my pure silver cables, there is audible hiss on my iem.

I tried both outputs and can hardly hear differences on my hd650 and hd800s. But im using RCA in to my CAN, i'll need to try 4.4mm input to see if there's more improvements.

I bought from here https://sgaudiohive.com/collections/allegro/products/allegro-interconnects?variant=28066173485136 There are few variations of the cable material, i option for a basic one because i feel its just a short IC.

I am expecting difference between RCA and balanced input. Otherwise what's setting a balanced AMP apart? I'm still awaiting my local maker for a custom 4.4mm to 4.4mm interconnect, it certainly is a niche cable at this time.

I would like to ask what are the sonic differences between using the RCA vs 4.4mm balanced input? Is there sonic upgrade if i connect RCA in to 4.4mm headphone out, as opposed to unbalanced out?

Just gotten my stack, ifi Zen DAC and ifi Zen CAN yesterday and had some good listening. Im using HD650 and I must say it pairs quite nicely. Actually the Zen DAC itself is already quite good, differences between DAC & CAN out is small. Oh remember to try the GTO filter, quite a lot of...

Definitely improves the sound, as compared to stock cable. Stock cables are too thin, resulting in loss of signal along the way. But if I could choose again, i'll pick a pure silver cable with TRRS termination. The mentor now sounds very balanced to me, as mentor is slightly V-shaped in...

I have the mentor with the SD and another silver cable, in all honesty and as per mentioned in the ZX2 thread, I don't hear much of the TRRS termination sound improvement. Plus the SD is SPC on the ground end, not totally silver, still, the mentor is one excellent iem which houses 10 drivers in...

Yup, really there isn't such a thing as "High-Res" audio. A sony digital player at $200 has that sticker as well. I have a Sony ZX-2 which also has the sticker, it means nothing. There's a bunch of good audio equipment not tagged as such.   On a side note, a predecessor-successor comparison...

Always thought the "Hi-Res Audio" is only part of Sony's gimmick... pretty interesting to see it on your box there. Congrats and do enjoy your HD800s!
