I see. Excuse me, it's just the first time I have seen agricultural used in that context.
Funny, you know, in ancient times, Naim was one of the most coloured sounding brand in the market with their system and SBL speakers, as warm and musical as they come. And conversely, there are tubes that are neutral, reference-like in timbre and tonality, fast and punchy, with some of the best transients in comparison with solid state; don't write all tubes off as warm and bloomy, though some can be so. Can't say that I can vouch for tubes being preferred or not for certain genres or individuals, other than, as with all things in life, do try it and lets see.
You mean the 4.4/4.4 interconnect? I have a several, I particularly like my old Wagnus ones and the latest is a bespoke 4.4 to an interchangeable 3.5/4.4 termination made for me by NightJar from a special speaker cable, quite one of a kind actually. I don't mind spending a few extra bucks on transducer cables; I have a few including the Orpheus and Centurion, but wouldn't couldn't pay their asking price for the same interconnect, I just don't believe that the difference from a 3-inch wire could justify the price tag. I will be trying the Centurion interconnect soon though, following my own advice, and lets see...
DC Ti is the titanium CIEM from Fitear. As like Wagnus cables, it's from Japan, cult-like almost and not a brand that Europeans will know too much about since they are pretty much sold in a few countries only, in Asia. You can check these brands out in their threads on this forum. Also part of the fun of this hobby to explore new stuff!
