  1. External cross overs

    I put my "econowave" speaker crossovers in external boxes to make it easy to dabble with active crossovers. They have been fine mounted in $5 jiffy boxes. No heat issues. It does mean there's extra "stuff" to deal with hanging around behind the speaker boxes...
  2. An old thread but I'll just mention I have the Jaycar unit and it is OK for my purposes. Though sometimes I have to give the mechanical switch a bit of a flick for it to click into place properly. I am using it as an input to a miniDSP active crossover that reclocks and resamples the input so it might be quite forgiving of the signal it is fed however. edit: I see Jaycar have discontinued the mechanical switch and replaced it with an active unit: https://www.jaycar.com.au/3-way-toslink-switch-with-ir/p/AC1594
  3. Time to finalise?

    My econowave Xovers in the tuning phase, a couple of years ago.. though I later spoiled the magic by assembling them into the PCBs seen at the bottom.
  4. Time to finalise?

    No, perhaps what I was suggesting wasn't clear... I wasn't saying get rid of the alligator clips, but remake them with different cable. I've been "evaluating" some super tweeters in my loungeroom setup for probably a year now... they are still sitting on top of the boxes connected via caps and alligator leads :-)
  5. Time to finalise?

    You need to redo the alligator clips with monster cable (tm)
  6. DIY disasters!

    I fried one of my Tripath amps trying to improve it by replacing the input caps..
  7. No worries. The kit I used to build mine was a low cost one from aliexpress (with a bunch of better quality locally sourced components as well). The KRELL badge on the cheap and cheerful JLH type Chinese amp is funny. I'd expect the quality control to be quite variable. I don't know much about the "Krell" KSA-5 sorry.
  8. Hi, no problems - my JLH 1969 is seeing daily use and continues to work fine driving high frequency drivers in an active crossover setup. I can't say.. I've filled my house with DIY audio gear and don't get out to listen to other stuff, so I don't have a reference point, plus I rarely run it full range. I use mine with very high sensitivity, high frequency only drivers, but while testing I had it connected to DSE bookshelf speakers of about 86 dB sensitivity and it was OK for low/medium volumes. So I think it would be OK for nearfield use with 90 dB speakers. I have seen online what appears to be a "cut down" version of this amp sold as a headphone amp. I haven't tried myself. http://www.diyaudio.com/forums/solid-state/172473-jlh-class-headphone-amplifier-2.html http://www.ebay.com/itm/ZEROZONE-JLH-Class-A-1969-Headphone-amplifier-kit-preamp-kit-DIY-/191844482763
  9. I think for off grid the high efficiency, and single ended power supply needs of some Class D chipsets might make them a good choice. I have been playing with my low cost "picnic blaster" system that uses an inexpensive TPA3116 amp that sounds surprisingly good for the price. I've been driving it from a 12V SLA battery at 24VDC to get maximum power from it, using 12V->24VDC "laptop adaptor" though the adaptor is a bit cheap and nasty. I just noticed the Sure Electronics site has some very interesting looking higher wattage 12VDC voltage converters.. I haven't used them myself but they look worth investigating: http://store3.sure-electronics.com/audio-oriented-power-supply-units These look great for upgrading my battery powered system to use beefier/better quality Class D amps that run from 36VDC or 48VDC. edit: although "picnic blaster" uses pretty average Pioneer car speakers I am quite sure it would sound fine with my better quality high sensitivity speakers.. but I don't want to take them outside.
  10. I concur. For the festy hall show despite clicking buy within minutes of the web site opening somehow I ended up only able to to get tickets way to the side where all I could hear was backwash reflections of the sound. This time I have a better position. I quite like the 2 new songs from them I have heard recently.
  11. Hi from Bangkok

    not major label stuff, but surprisingl amount of higher profile releases in some genres... http://www.nytimes.com/2016/08/20/arts/music/bandcamp-shopping-for-music.html
  13. I use these devices for my raspberry Pi audio player, and they are fine for the speed of flac playback or slower, I'm not sure about video speeds though. I'm using older (and slower?) models than the one in the link though. Quite sensitive to power boards, surge protectors etc. The network link they provide is slow but solid and reliable, compared to wifi, at least in my particular setup.
  14. +1 having the key bandwidth consuming & playback devices, on network cables, not wifi
  15. more eclectic than I was expecting, and nice to see MBV in there.
