So how many are coming ?

I'll get Adam (binary110) to chime in I know he is coming. He has even volunteered to work on the chain gang to get some of the stuff finished.

John (bearberry) seems to have fallen off the face of the earth.

Time to get out the radar and magnifying glasses.

Hi Guys,

George from exadevices (www.exadevices.com > Home) has expressed an interest in coming down from Toronto to see the show and demo his exaU2I and new DAC if people are interested.

What do you guys think?

Cheers,
Owen

 

[JohnTitor]

Wow, I'd be really interested to hear the exadevices stuff.

Don't make the trip on my account, but I'd certainly be happy to meet and chat with George.

Seems like there might be quite a few people.

Patrick.

 

[Kravchenko_Audio]

Fine with me!

Hi Guys,

I'm interested in Owen's LPUHP-16W and the LME49830 / Lateral Mosfets amplifiers. The PCB's are on their way, and I'm excited to build them. It will be fun come to your show, see the demos and exchange ideas. I will have with me an exaU2I, an e18 DAC, and my notebook with multichannel high-res files. If the schedule permits we can try digital crossovers and "audiophile-grade multichannel", if such a thing exists 🙂

Cheers,

George

Hi guys,

I'll be there for Sunday at least, hopefully Saturday too. Looking forward to another good time!

John

 

[JohnTitor]

I would really like to see (hear) a digital crossover in action. On the fly hi-res digital processing is one of the main reasons I got into diy audio.

I'm really starting to look forward to this.

 

[Kravchenko_Audio]

There will be at least one digital crossover. Possibly an RTA EQ.

 

[Kravchenko_Audio]

John ( bearberry) You is alive!

cheers wolfgang

Hi Pierre,

I'll be bringing along my latest and greatest speakers as well, and either day would work for a demo.

I also think George will be using these for his high-resolution audio playback demo with his DAC and I2S/USB stuff.

They're flat as can be from 25Hz up to over 40kHz, have incredibly low distortion and can play at ear splitting levels with my little 16W amps 🙂

Should be fun!

Cheers,
Owen

Owen, they're beauties ! I can't wait to hear them. Having said this, just to balance the weekend schedule-wise I would think that Sunday would work best IMO.

Hi Owen,

This is a very impressive frequency response. I am trying to figure out how to feed your driver files in one of the convolver plug-ins available for use with Foobar. Convolvers require impulse response saved as a WAV file with matching number of channels and sampling rate. I haven't done that before. My experience is limited to testing digital crossovers like Allocator and foo_dsp_xover.

I will have with me an exaU2I and e18 DAC. Hopefully we can figure out the connections at the event.

-Best,
George

Competition! Oh boy oh boy!

Looks very nice Owen. And good to see the 10's have a home now. Using a boosted alignment?
