Will Trade For: Nice USB portable dac
Will Ship To: Anywhere
Bought from http://www.head-fi.org/forum/thread/520926/fully-loaded-diy-kha-jaycar-hp-amp-uk in Nov last year. Now I no longer have a use for it, since I got a Audio-gd NFB-10WM.
More info on rockgrotto, there's a 91 page thread there and an entire section for the jaycar kit amps.
The amp has:
a) Audio-gd regulated PSU section
b) Audio-gd Discrete opamps, &/or LME49720 (depending whether you want it all discrete, or want to change the sound sig)
c) Premium caps (Nichicon Muse KZ, FG and Soniqs PXX polypropylene output caps. A full set of Russian PIO bypass caps at the bottom of the board.)
d) Alps 'Blue Velvet' RK27 pot
e) Neutrik locking jack and RCA sockets
f) WBA silver solder
g) HIFI 2000 "Galaxy Magiorato" 230 x 280mm case, with brushed aluminium front and top panels. (slight nicks on the back/front and top)
h) 220-240V fused socket with a switch at the back (on the power socket) and front.
No PSU noise or channel imbalance, very low noise floor. Neutral-dark sound, best suited to bright HP (although the Moon vs Sun opa will change the sound signature). The gain has been set for low impedance HP, you can swap 2 resistors to change it (gain is controlled by swapping R1 and R4 for lower or higher value resistors-currently set for 1.5k ohms).
I used it to drive my T5p, CD3000 and W5000 and it was great.
I traded the amp for about $500-600 headphones, so I'll part with it for:
$450,415,400,375,350 $320 (free pickup from Sydney castle hill) + shipping (25 within Australia, 60-75 for international). Add 2% paypal fees if using paypal.
