I'd be interested too

I'd likely be interested.

qusp and I should be there in about an hour ...

It's the curse of being an engineer, I simply overthink everything technical. Sorry for derailing the thread with a technical sideshow!!   The F5 is quite likely a very good amplifier for them, at just about any sane listening level. Me, I would love to have an F5, maybe one day I'll get to...

Quote: Run the numbers for the K1000 through the LPUHP (the amp in qusp's photo for those who haven't seen it before) spreadsheet that I sent you a while back ;) I might even do it tonight, it needs tweaking to take sensitivity in SPL/mW rather than 2.83V/1m ratings that I was using when...

Less than seven sleeps left. I posted a reminder on stereonet to see if anyone from there had forgotten about this.

This arrived today, expecting a new DAC board by the end of the week :)      

For USB I use one of these - http://luckit.biz/new/product/waveio/ I've also been interested in the (very recently updated) hiface board from acko at the bottom of this page - https://sites.google.com/site/ackodac/     I would recommend looking through photos of other diy dac hookups for...

Quote:     Yeah qusp's suggestion was stupid ... because scientific approach to electronics is insanity and never produced a good product ever. Right.    ALL that qusp/tintin/others and myself have said is that it may well be a waste of time to go into this project without having...

Quote: Hang on a second here. You have heard ~$1 ear buds. As well as a pair of over-priced-at-half-the-price noise cancelling Monster Audio Beats. Only ever listened to them from an ipood. From this you concluded that the only logical next step is to build your own from scratch? You...

Quote: Actually, part of that post was as a test for the young protagonist, it is important to be able to tell when advise given is good, misleading or outright bad. This is especially true when relying on the internet for knowledge. No-one here has submitted a resume, how is he to know who...

Yes, you will likely have to change the enclosure so yeah ....

Quote:     The measurements you take are relative to your budget. Ideally, if you're developing an audio product you would use an AudioPrecision meter, dscope or ADC/DAC plus mic combo of your choice that are able to meet the performance requirements (ie the measurement equipment will...

Quote:  OP = original poster (ie the person that made post #1, the first post)   Any old speaker to test is a waste of time, make it a speaker that you think might meet your general design specification and goals.
