Diy fest 2007

I was only able to attend on the saturday .....

I was a little early so had a chance to chat with a number of others waiting outside.

The construction standard was [on finished items] better than many of the small company products I've seen ....

Sound was a problem as the venue had huge vaulting rooms ...only the "pink room" had a normal height ceiling...

I was able to offer the services of my cdp as sources seemed thin on the ground.

In the afternoon I was able to lend Vakesh [hope thats the right spelling] my cd plus a couple of IC... to provide an alternate source to his lap top. As far as I could tell his home built amps ..an Aussie kit with belguim cases...should have writen the name down ..duh...with his open baffle speakers sound very good ...but the room accoustics really made it difficult to get any real feeling. I tried the little blue light ...but the room was about 5x the volume of a domestic living room ...with only the smallest effect I could tell [and I know what to listen for] .

After a few disc I swapped ic to the platalloys oddly these really helped tame the room. I was unable to do what I intended ...which was a simple switch of three identical ic's each with a different metalogy ....oh well

The presentation was very interesting ....negative and positive feedback in amps ....but some was rather over my head.

So just to say a big thank you to the organisers and those that that attend both with and without gear.

 

Hi Dev,

ZG members were very thin on the ground, only me and Pete really. Virtually everyone there was a DIYAudio member so most of the opinions and discussion has happened over there.

This link will take you to the start of the after event talk and also has a few pictures thrown in as well.

It was a great weekend that I think everyone thoroughly enjoyed.

 

Thanks ShinOBIWAN.

Guys, I've pruned this thread. Please keep this on topic and carry on arguing on the following thread:-

https://www.audio-forums.com/as-rediect/showthread.php?t=17037

 

Do people have any pictures from the DIY meet?

Any discussion of new products people had cooked up (with photos?)

 

Yeah there were a bunch of pics posted over on the DIYaudio Forum. The link is buried in this thread ShinOBIWAN posted but to save yu digging

The thread is worth reading too. There's some cool looking stuff there

 

3-way Audax based loudspeakers built by Al:






Audax 3-ways with rebuilt and modified TDL RTL3's.


Couple of preamps, the one on top is a Lightspeed which uses Light dependant resistors(I think!) and was designed by John Curl. The bottom is the Heretical and is designed by Stuart Yaniger(USA).


A headphone amp, not sure of the specifics but do remember it being a class-a design.


Al's Apple laptop serving as a source and supporting it is a Symasym power amp designed by Micheal Bittner of Germany.


Tim and me enjoying the sunshine and chatting about the dollar vs. pound exchange rate.


A few folks listening to "I will survive" or whatever its called, purely accidental of course!


Jan's highly modified Behringer DCX2496 with full remote control 6 channel preamp section, a decent analogue output stage and a Tentlabs clock. Very nice!


Hugo's monstrous class-A Aleph-X monoblocks. These were excellent amps with a stunning midrange.


Chris' 3-way Seas and Peerless design. Really nice chap who used to live in Australia. Great accent.


My half finished junk


Vik's Orions and accompanying kit. A setup that can reach into the stratosphere of performance but only with a half decent room




A room full of folks enjoying the Orions. Gordon, with eyes shut, looks to buzzing off the music.


I think this guy thought the photographer was going to try and steal whatever it is he was holding.

 

Chris' 6 channel Hypex UCD180 power amp.


Chris' surprisingly good Jordan JX92S transmission lines


Chirs' class A preamps. I think these were a Nelson Pass design but not sure.


Shot of lots of kit.


Another Nelson Pass Aleph amp. Bet you couldn't guess it was class A could you?


Orions playing in a better room but still far from perfect.


Heretical preamp and sysmasym amp.


A sub that sounded good and the heavy dance tracks we played. T'was built by Rich.

 

These look ace



Tell us some more.

 

beat me to it ....

the quality of the builds are better than some top line makes. imo

 

Yes, the bass drivers are curiously arranged.

 

It's a Linkwitz Orion Dev with dipole bass and open baffle mids and tweeter. A kit speaker from the US.

 

That's what intrigued me - open baffle with one bass driver driving forward and one driving back

 

Bit of very brief commentary added to the pics.

 

Thanks Mike and ShinOBIWAN for the explanations.

Googling revealed the following:-

No prpblem Dev, there's a few bits of kit that were camera shy and nobody managed a photo. These were a pair of open baffle designs using an 8" Lowther DX and a pair of 12" Goodmans Axiom for bass all driven by some very low powered tubes, a Fostex based full range transmission line that were beautifully built, a large 3-way design using Seas tweeter, PHL midrange and 2 Focal 10" in an Isobarik loading and finally a Tentlabs CD player.

 

The Orion uses the Seas Millenium tweeter, which is one I really like

https://secure.wilmslow-audio.co.uk...d/207?osCsid=9b410a39a45771a7c30f2deb0b06c30f

Also to be found on some Wilmslow speakers, the Williams Heart Speaker, and the small standmount that (I believe) Tom Tom had with a full Naim system at the heathrow show last year. I've forgotten the standmount's name.

Anyway, a really nice tweeter.

Just to be a pedant (why not), although the tweeter is in an open baffle as has been pointed out, being a sealed unit it isnt an open-air design like the mid range unit.

 

Kudos C10

Agreed. I believe this tweeter is also the reason for the success of the Art Emotion.

 

reckon you're right. It's got a nice non-harsh top end. quite crispy.

I mentally liken it to crispy duck





mmmmm crispy duck

 

How the hell can a driver make you think of crispy duck Chris?

 

I don't know.. I think I'm just hungry!

NB, I've just googled for a giggle, and it appears the Kudos C10/C20 use the Seas Crescendo tweeter, which is a slightly dearer but visually very similar driver to the millenium.

NB, Markus it was the C10 I was thinking of, thanks.
