That looks extremely good to me, much better then even my own. The price seems very fair.

 

[K3cT]

Damn good price.

 

[grawk]

That's a great price.

 

[dario]

it will be a very good match with my 650, right?

thanks for all the reply

 

[scootermafia]

Yeah the M3 I had really did well with my HD650s. That one has very nice parts.

Nananananana, my one was a steal.

NZ $437 = $US310

($US268 at time of purchase, exchange rate has gone up since)

Rockhopper M3 Headphone amp for sale - TradeMe.co.nz - New Zealand

 

[FallenAngel]

But did it have a Plitron toroid and Sigma11? Those add about $130 to cost.

 

[Shahrose]

Wow, best price I've seen for an M^3+Sigma11. Congrats.

 

[dario]

I hope to try it soon

, from what I have read over the included AD8610AR onother good possibility is to try the OPA627-637, I have from the zero the OPA627 (on "double" adapator) and two LT1364 I can try them or they are not ok (I need single opa627 and the lt1364 is not usable)?

Thanks to all.

 

[komi]

Awesome, in my opinion what ever you got from AMB LAB is good, that one with all these parts is even more ...

Way to go ...

A bit over a year ago, back when M3s weren't as much in demand and there were more builders still making them, there was one up in the for sale forum at $250 US + shipping which wasn't selling. I thought I'd try to bargain the price down but the seller wouldn't budge and I lost it. Kicking myself for not grabbing it now!
