Triode Wire Labs or NRG Custom The Five for my 300b SET tube amp?

LavriCable flies under the radar but their products punch WAY above their price. Their cables are 5N silver but just sound like music with excellent dynamics and detail. I’ve got several of their cables and many other very established members here have bought their cables and gush about how good they sound. At your price level you can buy their absolute top PC, and I think it’ll deliver exactly what you’re looking for in spades. Hope this helps, and best of luck.

Multiple bikes, but my main road bike is a Ventum NS1 with full Campy Super Record EPS, ENVE AR4.5's, Quarq power meter (with Absolute Black chain rings). My wife's main bike is a custom Parlee that she's had for years. A whopping sub 13lbs with 50mm carbon hoops, power meter, SR EPS, etc. Tri/du bikes are both Ventum One with SR EPS. All in all, about 14 bikes between us

That Fezzari bike looks absolutely sick, but the seat makes me think it feels like getting a prostate exam.  

@soix oh there's a cut out in the middle. Plus, your bib shorts have the padding so it can move with your body and chafe (which can happen with too much padding on the saddle itself). I've gone 100 miles + in one day with this saddle.

Got it.  The cutout in the middle seems key to especially male comfort/health.  And I forgot about biking shorts having padding, which I also own and are obviously key.  And I had no idea about the chaffing issue, but that makes total sense.
