sandyk Posted January 29, 2020 Share Posted January 29, 2020 I would be pleasantly surprised if Plissken even knows how to correctly drive his AKG K701 headphones. The ATH M70x doesn't have such a huge dip in the 5K to 10K area as the M50x either.

Numerous members at Rock Grotto which was mainly a Headphone Amplifier forum, owned AKG K701 headphones and confirmed that the AKG K701 sounded way more refined when driven from a 120 ohms source impedance. The part that I quoted actually came from Silicon Chip magazine (Australia) in their write up for their Studio Series -Stereo Headphone Amplifier which I also constructed back then, and was republished in the U.K. magazine Everyday Practical Electronjcs in 2008. More than 300 of my modified versions of this amplifier were made by Rock Grotto members world wide using kits from Jaycar and Altronics in Australia . It should be fairly easy to try an external headphone plug to stereo socket lead including the series 120 ohms resistors to see if this improves the sound of the AKG K701 as many other people have found . You could also experiment with different lower value resistors to see if you are able to achieve a more tonally balanced result with the AKG K701 in your own set up. plissken 1 How a Digital Audio file sounds, or a Digital Video file looks, is governed to a large extent by the Power Supply area.

Head Amp and Micro iDSD were 2 that I owned and quickly discarded at the $500 price point. Just doesn't pay to skimp on your headphone amplifier. Head-Fi meets highly recommended as a way to compare and learn whats possible for headphone playback, identify your preference with least money wasted on non successes. I have 3 friends from the USA that participate in Head-Fi Headphone meets, and several years ago I was invited to attend a lHeadFi meet in Richmond NSW Au. and bring along my DIY Headphone amplifier which was well received. One of the HeadFi members had already constructed my DIY version as presented in a U.K. based Audio Forum .

As I just explained to Jud in this post. It's something you proclaim to have area expertise in but yet fail to answer my simple question and instead you are now simply calling my setup that I used as 'mediocrity'. Now you aren't under any obligation to answer any question from any one. But the desperate ad-hom attacks should stop. Either meet me with excellent technical responses or don't. But your 'it's pos' attacks are about to stop. You brought me back into this thread of yours that I had ceased participating in, now you can clean up your own mess. I won't be taking any notice of your demands either.

It's about people using the "you're system isn't resolving enough" attack, often with the implied or explicit addition that the person being attacked can't afford a "proper" system. It may be phrased in terms of someone's kit, but it really is an attack on the person. It isn't necessarily an attack on the person , and is highly unlikely to be a suggestion that the person concerned can't afford a more expensive system. Many 100s of A.S. members for example, have demonstrated to their own satisfaction that commonly used computers such as the Mac Mini can have their audio markedly improved by retrofitting a John Swenson designed Linear PSU and Fan controller. Only those who believe that this kind of thing is Snake Oil are likely to see this as a personal attack about their system being inadequate.
