I thin witch hat did, unfortunately closed activity
Not IMO
Flashback offered a much cheaper range of interconnect
Also terminated for other brands than Naim.
Not sure Flashback sold speakerwire, at least not very expensive ones.
WH Phantom showed up to consist of $2/m Chinese cable.
Flashback had three honest i/c ranges
FB had a promt ship rate, I never read they failed with wrong deliveries, not the best WH reputation on that issue, WH took money and orders, long after they knew their bankrupt coming.
David was a true honest gentleman, RIP.
To be honest I wouldn't compare WH and Flashback at all, beside it was about cables.
