I have a pair of these tweeters that I don't want. One is excellent condition, the other not so - it had a repair and although it works I'm not convinced it's as good as it used to be. Anyway you can have them both if you want.

Tha following project seems to tick all the boxes. http://www.diyaudio.com/forums/digital-line-level/264743-hi-end-dsp-based-multi-channel-integrated-preamp-crossover-dac-project.html I hope it gets fully developed and becomes available.

I've built the UGS preamp (see the Pass section at DIYaudio). It has a lot of line level inputs and volume control. The volume control is a fixed resistor ladder arrangement controlled by an Atmel 64 chip. It works very well. However, I prefer the balanced output from my dac straight into the...

Hi Ed Did you get Traktion with the Behringer? If so is that able to do what you have done in Reaper? Aidan

Excellent work. I have been looking at digital crossovers for quite a while as I have had a similar project which has been on the go for a few years. At the moment the individual speakers are driven using an analogue xover which is fine. The xover has a pot for each channel and also one for each...

Russ Andrews used to have an upgrade scheme for this preamp. It recommended quite a few changes including inserting Schottky diodes. I performed all the changes on mine. The biggest difference came when I replaced all the caps that are in the signal path in series with the opamps. There are a...

These look great but surely not class A.

Used to have a 3C Primus with PA1, but have moved on. The PA1 easy beat a Tag Mclaren P60, but not a Nelson Pass F5. Now have 4 way active set up.

Here's another contender. I'm not sure whether boards are still available. http://www.diyaudio.com/forums/group-buys/74420-active-filter-board-gb.html They have provision for baffle step and other filters if needed.

A few years ago Rod Elliot sold some of his 4 way LR XO boards at a reduced price because there were some errors on them. I couldn't resist and have had great fun with them. I've bought several drivers cheap from eBay and played around. At the moment I'm using some ribbon tweeters; mid units...

Thanks for the heads up on these. I've just hit a pair for £85 BNIB. :D After some consideration I just ordered one of these: http://nwavguy.blogspot.co.uk/2011/07/o2-headphone-amp.html I'll report back when it arrives.

I'll take 20 matched.

Thanks for the link Martin - very interesting, and informative. I was envisaging a simple input buffer arrangement (B1 style) at input to JLH, not simply swapping a bjt for a fet.

Pass designs aren't noisy?!

Anyone know if there's there a version of the JLH with fet input?
