If nothing else, it could be turned into a real valve amplifier. There seems to be space for 5-10W output transformers. Lowest parts count would be a single ended amp regardless if it is in pentode or triode mode. Google RH86 if you are interested.

push on various points of the cans to change the angle and distance to your eardrum. I found a far "superior" geometry than the standard pads allowed. By compressing the pads in the front, i improved the bass dramatically (for my head).

I must say that I totally agree with your sentiments. I will also say that I choose to avoid apple products (so far ) because I consider them overpriced . However I just could not see where Dalethorn was coming from as it seemed to me that Apple would not try and get away with such a transparent scam that Dalethorn alleged. The explanation given in the link that I posted would seem to totally refute Dalethorn's claims but I await his response, perhaps he has taken into account the difference in decimal and binary measurement. Hi Alex30, actually the Faux Pas here is for those that have an 8GB iPhone. Generally they will have to backup everything (good to do anyway) and then wipe the phone clean as the IOS8 needs almost everything available for memory to update. After the update, there is room again to move stuff back. The additional memory is needed for the operating system swap and is what it is. There is nothing wrong with not wanting Apple products. I simply have a problem with plain bullsh1t arguments. If someone wants to explain what is wrong with Apple, there are enough truths and we do not need to make stuff up.

I don't understand the excitement. No one got screwed. Every single sold byte is there, physically and electrically. Those that have trouble with Apple can simply ignore it. There are all sorts of wonderful windows, android and misc. operating systems and other phones that have and need various amounts of memory. Choice is perhaps the greatest difference in our current stand of civilisation compared to earlier years - well for those of us not living in the Middle East in any case.
As someone who wire wrapped my own first 8kb memory upgrade for a Commodore VC20, anything purchased today is PURE LUXURY. I do not need 30GB+ of music/video/photos with me everywhere that I go. I think that we should count our blessings. The privilege to bitch is also something that builds with decadence. I am as guilty as anyone else. My fortune is not dependent on having or not having the newest and bestest.
If one was looking for an excuse to avoid Apple, there are far more "critical" things than criticising them for publishing memory specs like EVERY OTHER COMMERCIAL BUSINESS ON THE PLANET. But once we start, we discover that the competition is not really better, rather they have simply chosen a different set of things to like or bitch about.
I really resent calling Apple or any other "legal" business "pure evil". Hitler, Ghaddafi, Jack the Ripper, Bernie Madoff aren't even pure "evil" and they got where they were by NOT allowing choice.

Apple bashing is popular. I do not understand the bashing appeal. I have a 4s and use it as a metronome, tuner, calendar, opportunity to surf when away from home as well as a communication device with excellent coverage due to my provider - the german Telekom. The most used feature is the integration to my MacMini. All the stuff I need requires no manual to figure out how it works. The backups and media sharing through iTunes simply works. I could give a shit about what processor is inside or if it bends. All of the GearHead stuff does not apply to my use case. I have a dock (i20) from the Pure company that does an excellent job as a high quality portable source.
To be honest, I have the IOS8 update but have not needed any of the new features yet.

When I first got them, there was something missing - BASS. I knew about the break-in time (100 hours+) and let them run on moderately loud noise for a week. What I did do however was compress the earpads a bit (a couple of millimeters) and then the balance and tone were stunning and still are today. I really like to listen to headphones this way.
I have always wondered why high end headphones do not have adjustable earpads. No ones ear geometry are the same and even small tweaks in the positioning of a headphone in relation to the ear can change the sound from acceptable to incredible!

I've seen a good offer on the K702's and have decided to go with those after all. Am I mad? Yes of course. There is no decision more gratifying than the one that was made without comprimise. You aren't crazy, you are investing in your future. I think it is in the way of the music if we have that nagging thought that we did not buy what we knew was better. I have had the 701s for 10 years or so and every time I listen to them, I simply enjoy - because NOTHING is missing.

I just did some Infinity woofers. You glue the new surround to the cone and let it dry. Then you apply glue to the frame and move the surround about until you can push the cone in without it scraping. I used glue that takes 30 minutes to set. I exchanged the foam surround for rubber. No more rot after 5 years.

Actually, Scotland is in a great position now. Perhaps better than if the secessionists had won!

I have never heard of Grado cans being called "sweet" in spite of the top octave bite or DT770s sour due to the big bass.............

Did Stan ever get a can amp off the ground? Nothing that I read here sounded like alternative, product development or a business plan........
I do agree that EQ would be a nice thing to have. 2 parametric controls would be enough to flatten out most decent cans. If this was a commercial venture, measure a bunch of headphones and publish the frequency response and suggested correction.
In a previous life, I learned that it was even possible to optimise phono preamps for a specific cartridge. It can't be that tough to figure out if the issue is "driving" the headphones or frequency response due to impedance issues. I am sure that we don't "need" 6 amps for 6 headphones if music is our final goal.

They do it because they CAN and they could have it no other way. I find people with passion - interesting. Unfortunately, life catches up with some of them early..........

Will we need a UK subservient North Scotland too? - seems to work in Ireland.
I mean what can an independent Scotland accomplish outside that it couldn't manage IN the UK - step into the Euro union? Return to union run manufacturing? New Queen from the Stuart lineage?
Nothing against the Scots, I just don't see what the split can politically accomplish unless it is designed to let more Europe onto the island.

........... People who have years (decades) of computer experience may find this foreign, but they have to look at the big picture - that terrorists are everywhere and they poke into everything, so whatever you do while connected** to the Internet had better look "normal" to the authorities. **Now don't laugh, but there will come a time in the near future when having a computer that's not connected and approved for security will be considered very suspicious, and subject to seizure if the authorities learn of it. Those days are here already. Apply for a job in the US and you will be asked to disclose your user name for Facebook and Twitter. Don't have one? You won't get the job. Are you 14 years old and have no trace to a porn site - could be a profile problem........ I tried the imbedded update. It works - or at least the system did not crap out.

Thanks! I had a great day in the middle of Sweden on a big lake with my wife, our children and a bunch of guests. Good weather, food and drink. No audio for a whole week. I did use my Sony noise cancelling headphones in the airplane however.

hi Alex,
I will remain sceptical. It is not that I don't believe in interconnect differences, it is the single source...........
Power cords is another issue. In a studio we can run cable through shielded conduit, grounded everywhere. In the typical home, there is no significance in the last meter. Filters belong in the amplifier PS not the power cable. If we are using an UPS regenerator, then perhaps shielding would provide benefits in a noisy environment.
In any case, there is a specific context that has to go with any change, pimping is much different than rebalancing. I am happy that he is thinking about stuff like this. Keith Johnson, John Eargle and many others pioneered a lot of real benefits through engineering, not audiospeak. Their whitepapers are generally available.
I do a fair amount of recording myself (from the musicians side) and have not been able to place additional value on 4x recordings. The incredible damage of resampling however or digital EQ or normalizing volume digitally does take a noticable toll on the SQ. How many customers have real 4x playback-in the context of how "difficult" it is to get it right in the studio?
We need distribution of the raw data files, uncompressed, recorded as they sould be played back. With classical music we can get balanced recordings with minimal mikes and all modification in the analog domain. Perhaps a direct-to-ear concept would be marketable.
I will remain with my view: his success is based on incredible ears and communication skills. His "technology" posts are more like marketing material to me.

Although it is interesting to read what he writes, there are many issues where I seriously disagree. I sense a good deal of "hype" in the direction of "audiophool" speak. He does get great results in the studio, I am sure not for the simplistic reasons in his blog. I think he simply has tremendous ears - and a healthy commercial attitude. "High end" interconnects and supposed superiority in resolution make his product (the studio) surely more saleable,,,,,, For a very interesting view on how much resolution is enough, here is a very interesting article from Dan Lavry from Lavry Engineering - a DAC producer that would have a real interest in higher resolution if it yielded results....... lavryengineering.com/pdfs/lavry-sampling-theory.pdfThe continual plugs for Nordost interconnects are also interesting - with no context, sounds like a real marketing issue. There is a saying that a little knowledge is dangerous.............

Hi Robin
As an example, it should be relatively easy to DIY a small LM317T based regulator to supply clean +5V to the SSD from the +12V rail ? Regards Alex Already did that (well actually the JLH circuit that you have been advocating for a long time)! I have been following your posts in this erection for years........... The regulator board has SSD format and fits nicely in the MacMini.

The beauty of the MacMini is its size format, level of software integration, WAF and the remote control of iTunes with a simple iPod. I am long out of the Mac vs Win discussions. They don't lead anywhere as everyones mind is made up. My personal opinion is that Mac are less work to install and maintain, and as there are less choices due to Apples resrictive software policies, we don't muck around as much chasing fairy bits and bytes.
Yes, I am aware of the external PS and the credible reports about the improvements. I don't have a grand to sink in a PS right now as I have identified a couple of things that need to be done first.
If I change the PS, it will probably be a DIY solution. An external PS does comprimise the form factor......... I could envision an external PS in the MacMini format however...........
My MM is a Core i7 2.7gHz with a 128gB ssd. Wired gigabit ethernet to a NAS drive where my music files are stored.
