I have 20 yr old HD 560 ovation II's and they are super clear, great sound stage but lack bass if you ask me, a punch I like sometimes. I'm thinking HD 650 close to them but with bass or Momentums over ear more fun but less accurate you'd say I guess. Are the HD 650 worth $360 with no box, no original cable , new cable Clou Red JasPis cable. I can't decide that's a big jump from $240 range from where Momentums are going for
I know the specific ad you're referring to with that cable. If you're going to invest in an aftermarket cable it makes sense financially, but you can find almost-new examples for $330 all day long if you look hard enough. Replacement earpads are something like $60, and I think the ad you were referring to was in desperate need.
