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,   most of you probably know what crossfeed is, but have you ever heard its effects? Or have you ever been able to compare different implementations?   The basic theory behind crossfeed is quite simple, you may check out the “crossfeed” page at my website for info, if...

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...

Celebrating 6 years of Head-Fi Meier Audio introduces the Limited Edition HEADSIX (portable headphone amp) Head-Fi Support Sales Action Dear Headfellows, The Head-Fi jubileum amplifier from last year, the CORDA HEADFIVE, was a huge success. The revenues of these sales allowed Head-Fi...

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

Dear headfellows, This year (in June), Head-Fi exists 5 years. Years in which your favourite website has grown from a site for a small group of fanatics to one of the most popular audio sites in the world. I think this is worth celebrating! For the occasion a limited series of 500...

Dear headfellows, It is now 3 months ago that the CORDA ARIA hit the market and the amp has shown to be a tremendous success. Especially the sound quality through the analog inputs the amp has received many positive comments. The comments on the sound quality of the USB-DAC were not all...

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 raffle that we had for the victims of the tsunami was a great success. Now disaster has struck again. The hurricane Katrina has caused incredible pain and suffer. Time for another lottery! I have another PREHEAD MkII prototype left and this one will be used to raise...

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, Everytime when a new amplifier is being designed I make 1 or 2 prototypes for testing and verification. After the design phase is over these amps are normally given as a present to my friends. Fortunately I have many friends, but not everyone needs an amp and quite a few...

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...
