Hello. Here are my thoughts about the my new AKG K26P against my old K26P. First of all by "the old" I mean the cans with the old pouch with the zip, the "new ones" are with the pouch, closing by strings. When I first got my "old" AKG's some one year ago I was initialy extremely disapointed...

Hi. I was wondering whether IRIVER iFP-180 is a good choice for a DAP?? They have this one in a local shop for ar. $80 and I don't want to spend more. I want a cheap player with FM radio. My main goal is good sound quality and robustnes. The alternatives are some of the cheap Samsung and LG...

Hi, guys. This would be the first thread started by me. Today I read the Jan Meier's thread about the batch of 18 HE90's.(Excuse my ignorance, I heard about it sometime but after all the price equals my year's salary, so...) So at the end of the thread was stated, that the first of the Senns...

Has anyone seen or experienced them? I've just seen them on the beyer's site alongside the known rsx660 - http://www.beyerdynamic.com/com/maer...eets/djx_1.htm

Hi. I'm maybe a little out of touch with the subject, but is there any power supply made for the Dynahi? I mean something specially made for the Dynahi. As it turns out I can get the parts more easily the say PPA etc. and really love the chalenge presented by this project. But I want it to be...

Hi. How can I change my DT880' pads left and right. I want to do it because I wear glasses and they have already made a mark on the pads. Or rotate them 180 degrees? How can I dissasemble the pads? Thanks

Hi. I recently discovered that Jan Meier uses high bandwidth mode for BUF634P in Corda Ha1 Mk II (according to the article on his site). So I made a jumper between V- and BW pins on my buffers (self built PCB for the Corda). The sound (I thin so) became more thin and shrill, there is maybe more...

Hi. I recently built a Corda Ha1 MkII amplifier exactly according to Jan Meier's instructions and I must say that I'm impresed with it. Thanks again Jan. Very clean sound, no distortions and hum at all. I've made my own design of the PCB and the opamps are on sockets. It's almost there in terms...

OK. Can I use usual torroidal transformer and wind the necessary count of turns of isolated wire to use it as a secondary filament winding? Has anybody tried it? Thanks

Hi. I live in Bulgaria and yesterday after going to the local electronics shop I saw a Toshiba SD140 DVD player. On the front there was "24 bit 192kHz high quality audio" written. Is that model comparable to the already famous (in Head-Fi ) Toshiba SD4900 and 3750 (or something like that). I...

Sorry for the stupid question, but would 16V electrolytic capacitors (3300uF and 2200uF) suffice for the power supply of the Corda Ha1 mkII? According to the schematic one of the capacitos is between +15V and gnd and the other between -15V and gnd. Am I right? I don't want to blow the caps or...

Hi. i was wondering what YOU as a DIYers think is a proper PCB layout - especially for headphone amplifier. Questions like: How you route the input signals to the potentiometer? Should I avoid routing signals under a toroidal transformer (power supply)? Which are the elements that cause most...

Hi. I am having difficulties finding polystyrol or polystyrene capacitors in the 10pF - 47pF range. They are used in the Jan Meier's design of Corda Ha1 MkII - 10 pF and 47pF. I could only find 47pF WIMA capacitors at Reichelt (German online electronic shop) only later they told they don't ship...

Hi. I'm new to the world of headphone amplifier building and currently trying to build a Corda HA1 MkII. I've already ordered the parts and have several questions regarding building this amp. Any answers are welcome. 1. What is a star grounding and most particularly how do I implement it on a...

Hi. I'm trying to build a Corda HA1 myself and was wondering whether I should build the enhanced bass or the normal crossfeed version. I have Beyer DT880 phones and am definitely not a BassHead. Thanks in advance.
