Thats the thing. Way too open ended. Dont really understand the true meaning.

How much to build/ buy pimeta?

If the price of the amp falls within the amount that i have, i might consider buying it to test out. Spend too much already. Anyway how is the speed? Im in seriious need of a fast amp for my jh. What 600 ohm headphone you have tested now.

i think the only 600ohmers i know of are the DT770/880/990 series and T1. HE-5 / HE-6 & LCD-2 are power hungry (low efficiency) but are not 600ohms.

using standard components recommended by tangent, maybe around 300-400.

but if using lipo battery and custom enclosure (like i did), you might ended up in the RM600 price range

using ad8620, pimeta is very neutral and transparant. neutral with a hint of brightness. speed is very good. no hiss even with phonak or my low impedance im716

i once owned RSA Protector and to me pimeta is the better amp

plus, this thing drives my hd580 effortlessly with ipod as the source


hongrui, if you have o2, please let me try it for some time

if i cn get it below rm 400 completed i'll just buy n do a review n keep it

Of course u can....

ok pm me details ok thnx man n power up full size ? i mean have power for up to how many ohm? i know its kinda personal preference but just roughly cn it drive?

Well update u after meet another nearby forumer,as so far only tested ATH-M50 & T1 only...

wow if it can give dynamics to the t1 that shows something

AC adapter powered only..... ,dont even think ab batteries....but even Graham Slee also CANT drive the T1 well....

ooooh we're designing the product with approval of nwaguy..
currently doing the industrial design for the product.

It's all planned for 2012 even the ODA

i don't have the o2. hehehe no tube so no love from me.

omg this is awesome..

what's in the DAC section? the ODAC?

will the LOD input tap the digital signal from the ipod?

Digital signal there is a special chip that is license by apple.
Plus need to pay royalities... mahaal siol.

We small company cannot sell alot of things like ALO/Wadia/Fostex pricing..
We are just aiming to use it as a Laptop accessories for Uni students who are away from home in boarding homes

Wish that it isn't the Tenor chip,but think it's possibly the TI or XMOS.....although Nwavguy didn't mention at his blog

Opps,i mean the USB DAC chip,NOT the LOD...

Already got a complete 96/24 USB DAC on my design desk,but no time to implement it.... ,O2 come first....

Some forumers already got the blank PCBs,not sure they build it already or not....

our faceplate and venting design..
