I use Nordost Heimdall/Frey II wall to speaker.
You need to try it yourself. SQ is subjective. Only your ears are qualified to determine "too bright" or "fatiguing". Get used, much easier on the wallet. Negotiate towards half MSRP.
You can always sell it if your ears to agree.
Your concern is flat cable, I would lean toward BH. IMO the difference between BH/Heimdall will be subtle. The Nordost philosophy is start with the power cord for noticeable improvement(if any). Also look at the Purple Flair.
