squalle

suggestion: just open up a new thread coz virgo and MJ are not portable. so ppl might miss it

eh so 4 sporta pros? btw, afbug, the sportapros link from amazon, it's also being sold by JR. so yeah, LOL, we have to get them from JR. so, do you still want the 75?

most PROBABLY will order tomorrow night kross: will you be around tmr noon? plan to pass u the parts

transfer would do for deposit, to be fair, maybe around 75% of the item price. the shipping and handling from both sides (online store and Vpost) I'll handle first. then will show full disclosure when I've got to know the details. zephyr and afbug: where do u guys stay? I am around boon lay. for kross, I can meet him easily then maybe need ur guys' contact numbers too

k so for 3 of us, all are getting sporta pros wat abt u afbug?

haha I've talked to kross I think we both are getting sporta pros so how abt Zephyron? 35? porta pro2?

I think shipping shared by number of items purchased would be fair enough unless, the item's a lot larger or a lot heavier, which I foresee would not be the case hmm, so shall I proceed with just 4 of us? wat shd I buy? LOL 35? 75? sporta pro? pp2? abt the ksc75, yea I'd think the free shipping from amazon itself would be good will try to finalize ASAP well, how long more shall we wait for more to jump in?

ok as of now there are 4 people already still missing a few... have they already "donated" to local sellers? LOL

hmm yea gonna do it if enough people interested where are those guys LOL

thanks afbug and yea dang it's gone up to 19.99

views on the comparison of the koss ksc35, ksc75, porta pro, sporta pro http://www6.head-fi.org/forums/showpost.ph...31&postcount=14

sporta pros at 12.99 at J&R http://www.jr.com/JRProductPage.process?Product=24803 so how to continue from here? ksc35? sporta pros? ksc75? is there enough buyers around? can I have a raise of hands of those who wanna get them from OVERSEAS. and please, respect the decision of us who wanna get from OVERSEAS instead of locally

hmm PCB working but may come out with another rev

Then choosing the amazon's ksc75 would be better choice afbug: pls advise me regarding the vpost usa. I still dun get it on how they charge. would it be possible to closely estimate how much shipping to sg would cost before vpost really charges? If everything can be clear cut then I'd be willing to help out but, maybe I'd req some deposit for those who wanna order wat do u think? pm me or anything la

yea maybe you can share shipping together with ppl that want the ksc75 too as of now, pricing wise, ksc35 aint worth it man ksc75 is cheaper than the 35 where they have the same driver, but IMO ksc75 is better in build quality. afbug, maybe you can initiate the group buy from amazon, for either ksc75 or 35

neutralzz: taken from the new hall? u gonna stay there?

1. Yes the Pimeta costs more in parts compared to the SOHA 2. Small and weak? A completely uninformed and ignorant statement. Have you even listened to one? yea I got a friend who got a PIMETA and yea it's weak as compared to power mosfet how many amperes can it put out? :D hmm wrong question.. shd be, just how many mili amperes can it put out? remember, the thread starter said something abt bookshelves. which in this case, the buf634 is obviously too weak to power that but, if you would say to put a power amp after the pimeta, then that doesnt count anymore as pimeta, as what it's designed for, is too weak to drive a pair of speakers ADD: for SOHA, you can easily change its output stage to be buffered by a power mosfet. whereas pimeta, as it comes from tangent, how can you put a power mosfet in? or you would rather put 4 buf634? 11 bux each.. and can only give you about 1A so I hope you get where I'm getting at and that's also why I suggest M3 rather than a pimeta. IMO, pimeta is just a 3 channel CMOY with output buffer.

hmmm IIRC, electrolytic caps would die earlier than the tubes. and to change tubes is a simple matter Qsilver if u wanna power up a pair of speakers, then you cant use PIMETA. go for M3, maybe tweak it for higher power. from here: http://headwize.com/ubb/showpost.php?fnum=...=47239&fpage=21

PIMETA n PPA cost estimates : http://www6.head-fi.org/forums/showthread.php?t=164019 whereas SOHA, using non boutique stuffs, can be had for around 60-80 sound wise, whether you like it or not, depends whether you like tube sound but yea, I support you doing M3. it seems to be of superior design compared to PIMETA. btw, you're not thinking making it portable, are you?

errr PIMETA cheap? IIRC, it costs more than a SOHA and it's still made of wimpy ICs, small and weak

hold up on SOHA me and siriuz making a PCB 1st prototype was done. but hmm we decided to come out with 2nd rev with different method of making the PCB too so yea, just wait for news of it btw, SOHA is relatively cheap and easy even to do ptp. EDIT: just saw that M3 has mosfet output stage, but it's push pull. so it's worth a try PIMETA uses IC packaged buffer. so you might want something better if you should have to get another ss amp, why not try dynalo. a lot better, a lot more robust, macho amp but it'll cost more than a SOHA I'd say SOHA at its current state is rather weak. the output buffer is only an OPA2134, with max current delivery of 40mA only but, as of all DIY thing, you can mod it. like, putting MOSFET power stage there

heatsinks (for mosfets and LM317 CCS) are big and heavy. heavy enuff that I wasnt careful last time that it broke my regulator's legs but hmm now all is well the mosfet stage doesnt change anything, which wat it supposed to be IMO oh to cool the whole thing down, I have this 80mm PC case fan blowing towards all the heatsinks total I have 4 big sinks, and 4 smaller ones for my PSU regulators

btw, I've managed to get my MOSFET-based power stage up and running and I just received 2 more tubes, GE 5963 and GE 5814 currently rolling the 5 different tubes i have

hmm i think now if i jump in, we have 4 persons already? kross, u organize la haha

if voltage stuck, then the resistor to set the ref voltage for the regulator is toasted but hmm, find out how that can happen short somewhere? due to wat? haha maybe some alien has gone into the case
