Planning to sell my PPAv2

Opamp L OPA627

High Quality caps: wima, Rubycon and Duorex

Note: This amp is preset for low gain. For high gain, resistor change is needed.

Price $230

I managed to partly build the SOHA, in my preference I will still think SOHA is more value and performance wise is almost the same as millet

Any idea where to get them now.

I think this is way out. My ear starting to go bonkers.

Any idea where to go for ear testing.

When are you going down to koba. It been a lot time since i done DIY.

My first project is cmoy2, which i instantly upgrade to PPAv2 den tried my hand on a SOHA den i quit due to wheeing problems.

Can spare you some opamp provided i can find it. 2132 2134

hmm i still haven got my board yet.... hope to get it this time

Look normal to me...

I still haven got my PCB yet.. coz i miss out the collection that time...

toroidal transformer i got no idea how to get it in Singapore. For my PPA mine is a DC adaptor which i pass a tread through it...

But den Um1 shouldnt be used with amp when coupled with U3. The sensitivity of UM1 is enough to be powered loud enough. Unless your using a Ipod line out where a amp is really needed

I have this issue with my PPA and ms-1... But it is the gain of amp that caused the problem caused my PPA is spec for low Z headphones. By itself, U3 produced 60mw. of power, but the amp may not be able to produce that type of power since your is portable. So the issue is the amp.

Alessandro Ms-1 is Alessandro entry level headset. Grado and Alessandro look the same but I prefer MS-1 for the neutral sound. Ms-1 is like a SR80 SR125 equal.

Um1 is quite durable if i am correct....

in SLS... btw the pad oringal pricing is only like $8 - $12?

Do you all install the own-cut hole facing out or the precut hole facing out.

You need to have a isolated output. If i remember PPA use TLE to as a voltage splitter thus creating a virtual ground. The earth ground is different from the virtual ground.

Wah got ang mo version bo....

Will be there until wat time????

I built v2 . I think wanna try out the difference of descrete buffer and glassman buffer

No earth ground? would it be a little dangerous...

I using nothing now... anyway i just call boonco... tml they not open.

Just now I do a force format using the logical disk manager.. now my U3 works again

i think i screw up mine also... spolit font and windows laggy

wanna to meet up to go together

Foobar decoder is much betta den winamp

go to http://www.iaudiophile.net/forums/forumdisplay.php?f=38

I remember they have a fix for it regrading upgrade the fw twice or reformating the U3

In all sense a full size MS-1 is really the way to go here ...

That switch is nice where do it got it from?
