Oyaide Cables

My $0.02 worth - they don't have a consistent house sound, but rather have models that cater to different taste. Some can be quite bright, while some can be full and rich.

I only have experience with their ICs and power cords. But the Tunami Terzo or the AR / AZ 910 are detailed yet super duper smooth and grainless. Warm and rich power cord ? That would be the Tunami GPX-R V2.  

Since there is some interest in Oyaide, I'll share my thoughts on the various Oyaide cables I've tried. I'm in Singapore, and we have a local dealer that makes sourcing their cables easy.

Power Cords

PA23 - Thinner than the monstrous Tunami. Good highs but a bit lightweight sounding in the bass

Black Mamba V2 - Quite neutral and detailed. Super value for money. Not as heavy handed as the Tunami.

Tunami GPX - Warm tone. Very low noise floor and very powerful bass. Some may find the top-end a bit lacking 

Tunami GPX-V2 - Improvement over the original Tunami. This is more open sounding.

Interconnects

Tunami Terzo V2 - Detailed and super smooth and laidback.

AZ910 - Similar to the Terzo V2 but with more detail.

Digital Cable

DB/DR-510 - This is the FTVS-510 bulk 75 ohm pure silver core cable with Oyaide's BNC / RCA plug with pure silver center pins. These aren't bright sounding at all, but instead have a high detailed yet warm and full balance.
