Count me in. I can bring a pair of K-1000 if you like me to. Need to find suitable amp to power, my Fisher 800C that used to power them is dead.

Count me in too.

I quote from the site: "The Panache headphone output does not differ from the main output path except for the addition of a simple protection device." Which probably translates to resistive network derivation of headphone output from the loudspeaker output. That doesn't mean it's bad. But...

You can get a linear ±15 VDC/1.5A at Digikey (Condor or Power-One) for aprox. $60. The Medical rated Condor goes for $75. Any luck with the op-amps?

Benchmark has a combo DAC/Headphone Amp that got pretty good reviews. http://www.benchmarkmedia.com/digital/dac1/default.asp The HPA-2 Headphone Amp picture and specs are below. It's available as standalone for (no PSU) for $150. http://www.benchmarkmedia.com/interf...a2/default.asp I can...

Amps need a sort period of time to reach thermal stabilization and headphones, having moving parts, can have their mechanical properties shift a bit. The resulting changes do not always mean better sound. If something sounds bad initially to you it's rather unlikely to change through "burning...

I seriously doubt that you know how to experiment with anything since the concepts or measurable and repeatable escape you. And I will leave you all with this diamond in the rough: Quote: Originally posted by JaZZ It may be that it's you who's not willing to free yourself from...

To Jazz: Using sinewaves is the only way to induce repeatable and accurate harmonic distortion levels for this test. Their power is their simplicity. If you cannot detect 1% distortion level using a simple sinewave, you have no chance with a complex waveform. Recorded music is of no help...

I would suggest this test to Jazz, if you have a good sound card and a software that can generate sinewaves try to find your threshold of hearing detecting harmonic distortion. I could suggest something like a 1KHz fundamental and a set of harmonics (maybe simulate the Stereoplay curves?). I...

Ok, so your understanding is that theories are self-sustained with no need of proof. Interesting. So the Stereoplay documentation (the excerpts that you provided) are there just to support their colorful pages? Let's assume that you are trying to analyze scientific data, and complex data at...

Ok, I'll be .....sort Streoplay's systematic analysis is not new. The graphs and the info that you posted are incomplete (at least) to support any theory (pretty colored charts do not constitute proof). I am open to all theories as long as there is a true scientific method used to prove...

Maybe this kind of measurements are a breakthrough for Stereoplay. Audio engineers used spectrum analyzers like the HP-3585A with an HP-IB interface to a computer to analyze data further without "Sisyphean labor". Also you state that you are not an electronics expert but you are ready to accept...

You could try http://www.acousticsounds.com http://www.amusicdirect.com for a list of high quality recordings, and you will notice that a lot of them are issued by standard labels. If you could elaborate on what you are looking for I may be able to be more specific. Gallaine: I agree on...
