Dear friends, here I come with a somewhat unusual request. And the reason is that I'm currently working on a somewhat unusual device. It's a signal processor that allows to add crossfeed, tone controls, reverb, bass enhancement, ... to a digital audio-signal without the need of a PC. This...

Dear headfellows,   a couple of days ago I got a note from the Beyerdynamic distributor. A new improved version of the T1 will hit the market soon.   First devices have been promised to me by he end of August. I hope Beyerdynamic will be able to deliver.   I will post some impressions as...

Dear headfellows,   a couple of days ago I got a note from the Beyerdynamic distributor. A new improved version of the T1 will hit the market soon. Technical details can be found at:   http://www.meier-audio.homepage.t-online.de/newt1.pdf   Sorry, it's in German but I'm sure some of you...

Dear headfellows,   People who check my website more frequently may have noticed that over the last few months various models became sold-out and have not yet been replaced. This has led to many speculations and questions whether or not I will continue to produce headphone-amplifiers.  ...

Dear Headfellows, Some of you may remember that a few years ago I did give away a number of PCBs for a small stationary amplifier as well as for a passive crossfeed filter. These parts were leftovers from some previous production runs and enabled various DIY-people to make their own gear more...

Dear Headfellows, The last two months I got several mails from people who had compared the crossfeed functionality of the Headphonia amplifiers to that of the PORTA CORDA. According to them the two filters sound surprisingly similar. Two weeks ago I was able to organize myself an...

Okay, today it's the 19th and it will take one more day before Head-Fi really exists 5 years. But I simply wanted to be the first. Jude congratulations with 5 years of good work. And may Head-Fi be as vital in the next 5 years to come! Jan

...amps are expected to be ready by the beginning of July (and there's no guarantee that this deadline will be really met)! Cheers Jan Meier ********************************* Update November 18th: 472 amps have been sold. 28 amps have been made a reservation for. 0 amps are still...

...Of course this thread is not limited to experiences with the CORDA ARIA only. Any USB-DAC will react very similar to such optimisation efforts. ** While using an USB-DAC like the ARIA it is possible to control the sound volume in three ways. 1.Change the analog amplification factor by...

Dear Headfellows, All is well that ends well! (i.e. no PCBs left anymore!) :-) Jan

Dear headphone-fellows, All is well that ends well! This jubileum sales has been closed. Cheers Jan

Dear Headfellows, The CORDA prototype raffle as well as the January-sales action have been a great success. A total of EUR 4705,- / $ 6120,- has been collected that will be donated to a home for parentless children on Sri-Lanka. A great thank you to Jude and all other people that made this...

Don't forget, this one will end by January 31st: http://www4.head-fi.org/forums/showthread.php?t=101545 Be generous! :-) Jan

Dear Headfellows, I just wanted to let you know that Michael and I smoked our pipe of peace. We agreed that Michael will change his website and provide you with instructions on how to make your own passive crossfeed filter. I've contributed some of my own tricks to improve sound quality...

Dear Headfellows, As many of you will know I started my Headwize/Head-Fi contributions by publishing various designs on Headwize. The most popular of these were crossfeed filters that relieve some of the problems associated with the extreme channel separation of headphones. These filters are...

Dear Headfellows, I just updated the article on the DIY-headamp on my homepage with the schematics of the HA-1 MkII. http://home.t-online.de/home/meier-audio/headamp.htm Enjoy! Jan

Dear Headfellows, At the last IFA-show in Berlin the Sennheiser stand also showed one of the Orpheus headphone systems. Unfortunately the system wasn't connected and but when I discussed the system with one of the Sennheiser representatives he kindly offered to send me the unit just for a few...

Dear Headfellows, We don't have many Head-Fi members in Europa and it has shown to be rather difficult to organize a European meeting. However, next week I'll be getting a Sennheiser Orpheus for demonstration purposes and thought this occasion to be too good. Therefore, if you like to hear...

Dear Headfellows, Yesterday they finally arrived, those long awaited HD650s! I gave them a thorough 36 hours break-in and wanted to share my impressions with you. It's not an extended review though. I leave that up to people like Jude and all the others that soon will have their new toys at...

Dear Headfellows, Just a few picture-impressions of the IFA-Berlin. Sennheiser Orpheus in combination with a Burmester CD-player. Unfortunately there was too much background-noise to get a good impression on the sound, but it sure looks good. The Sennheiser representative offered to send...

Dear Headfellows, A few weeks ago I got a call from Mr Wilberg, the general-manager of Ultrasone. During our conversation he talked very enthusiastically about a new version of their closed headphone, the HFI-650 DVD Edition. As I'm quite a fan of the regular HFI-650 (Trackmaster) you might...
