  1. Thats great David. I have some Taiwanese versions of similar RCA sockets and i really had to pump up the temperature of my iron and ended up folding the wire ends to make them thicker. I have just purchased some Aurealis interconnects and speaker cables that us litz silver and copper. Very nice balance, so yours should be excellent. Cheers, Rob
  2. Nice work! I tried the Dueland 16AWG on my StereoCoffee board inputs and outputs but found it actually muddied the transparency slightly and enhanced bass, as they tend to do when used as speaker wiring. The muddiness was especially noticeable with my DIY 505 Mini ESL panels. Over the last few weeks I have built simulated litz cable using four strands of Teflon insulated 30AWG Kynar tinned copper wrapping wire from Jaycar which is twisted tightly. Its a bugger to trying to strip off the teflon so you will probably break a few before you get the hang of it. You can get 30 metres for under $18 so you will never run out. Make one lead about 80mm for each LDR board input and output. For consistent results I found its best to have the thinner wire touching the silver edge of the input/output lead holes on the LDR board when you solder it. The result is even better transparency than silver but a tighter sound with precise width and depth. I find that bass texture has improved too. I'm getting wall to wall width and precise positioning on appropriate tracks. If you want to fatten up the sound try eight strands instead of four. Recently, I wound a double strand of insulated silver wire around the four strand leads to add a bit more warmth. Strangely, I found that two strands to the output RCA improved musicality. Of course, you might have different tastes and the rest of your system mightn't sound right but it's worth a shot and doesn't cost much. The great thing with StereoCoffee is that you can tweak inputs and output to get the exact sound you want in a few minutes. Have fun! Cheers, Rob
  3. If you don't follow the crowd, you could take a listen to 2.5 Neat Acoustics Iota ALPHA speakers. Virtually unknown in Australia and manufactured in the UK. I stumbled across them at my local dealer for under $2500 a pair. They don't need stands. I was looking at a replacement to my ESLs and these are sounding phenomenal at decent volume levels. My REL subs aren't necessary any more. My listening area has a tile floor and 3 sides of windows. Phase problems finally overcame my patience despite still being filled with awe by the magic my ESLs. I didn't want speakers that pump sound forward. Holographic imaging and sweet realistic mids plus BIG DEEP bass are extracted from a downward firing woofer. A 45 degree firing mid driver and Planar Magnetic tweeter provide an ESL a quality with that magic wide sound stage with more smoothness. The catch? You won't notice them because they are only 500mm tall !!! But when you hear them they are as tall as your ceiling. Audio Genesis in Melbourne have them I believe. They have been getting rave reviews in Europe: https://www.stereophile.com/content/neat-acoustics-iota-alpha-loudspeaker If you just want to hear beautiful music see if you can get an audition. You won't believe your ears. Cheers, Rob
  4. How can you judge a StereoCoffee or any other equipment without hearing it, especially the 2020B update?
  5. Hi M. I have had the opportunity to test around 15 to 20 upgrades to the StereoCoffee over the last 3 years and seen it evolve from a good LDR passive preamp to something very special that gives me the most dynamic, detailed and beautiful music from a background of silent blackness. So what is the benefit of this black background? The uncanny background silence is there at ALL volume levels and this lets me hear deeper into the background than I ever thought possible. It's so silent I often get startled when the first sound of a track appears out of nowhere. There are a few technical experts out there in audio land who criticise LDR preamps without having auditioned the 2020 StereoCoffee, which now takes pride of place in the equipment racks of some serious Australian and international audiophiles running in harmony with expensive equipment chosen for its superior audio performance. Any equipment can fail and I had an input LDR die, which is very unusual, so not many owners, if any, have experienced this situation. It didn't stop me enjoying my music because the standard StereoCoffee has 3 separate inputs which are switched on or off, depending on which input you choose to use. I just moved my interconnects to an unused input and was back in action immediately. Do any other preamps provide that handy capability? I contacted Chris the next day and he sent me an LDR replacement board while I kept enjoying my music. Having given my opinion you still need to ensure the StereoCoffee is suitable for your needs and I know from experience that Chris will be happy to give you honest advice without any pressure. Have fun. Cheers, Rob
  6. Hi Peter. I think the 3 input DIY boards are around $350 and prebuilt unit around $600. You would need to ask Chris as he customises boards. Cheers, Rob
  7. I don't know which passive preamp/attenuators you have auditioned but the bottom photo in this post from SteveM shows my own tiny timber faced 2020B StereoCoffee LDR PASSIVE preamp with some very high end equipment for company. Other passive preamps I have heard were good but this one is on another level compared to other passive preamps and is absolutely worth auditioning, especially if you are 'in it for the music'. Musical reality is where this LDR preamp excels. My 2020B StereoCoffee is on loan to SteveM at the moment while his is being built but will be available for audition when it is returns if you are interested. Cheers, Rob
  8. I have tested CloneNote, LightSpeed and StereoCoffee. However, StereoCoffee has evolved into a piece of equipment that is being taken seriously and being enjoyed by serious experienced audiophiles with glowing reports. The 2020 versions are much more refined that earlier versions which also sound superb. Cheers, Rob
  9. Steve. Seeing my tiny StereoCoffee preamp build with its cheap silver knobs sitting there in that company makes me feel like a proud dad. I reckon that's a win for me! Pity I'm too far away to enjoy it on your system. Cheers, Rob
  10. These custom built SB Acoustics designed ARA white enclosure/speakers/crossover are available from Wagner On Line in kit form. They use top of the line Satori woofers and tweeters. I had to wait 4 months for the enclosures to come from Europe. Price would be around $2000. Enclosures with quality fittings $800. Crossovers $350 pair. Satori Mid/Woofers $500 pair. Satori silk domed tweeters $400 pair. They are about 550mm tall and they will require substantial stands because they are heavy. Just assemble them with push fit connectors and you are in business. I am using mine as bass drivers without tweeters for my Australian ER Audio ESL kit mini panels, bi-amped with Hypexes, StereoCoffee LDR passive preamp and active crossovers. Mine are sitting on a diy platform with aluminium feet. Cheers, Rob
  11. Hi all. Yes, I made a set of speaker connects with Uriah's insulated foil. I found them really excellent with my LD50s but moved over the Deuland tinned copper when I built my DIY hybrid ESL mini panel kits. Unfortunately I found they were bit too transparent with them. They were terminated with silver plated wire that was looped and fanned out flat then soldered to each cable with a big glug of solder using heat torch. The hardest bit was burning off the strong insulation coating. Deuland interconnects are terminate with inexpensive z plugs with screw connections from Selbys. They work fine. I still have the foils but it has been cut down to 2 metre lengths but I think I still have some spare lengths which could be soldered on. Shrink wrap with adhesive inside insulate the terminals. Hope this helps somehow. Cheers, Rob
  12. X-Kitz have great performing USA made 24dB Linkwitz active crossover modules for bi-amping. Mine cost $150 a pair delivered and were simple to set up. Bass, treble output levels and BSC can be adjusted by ear with 20 turn trim pots while you listen. A crossover module is supplied, you just choose the value you want when you order. You can make up your own plug in crossover modules with any crossover point by adding 20 1/4 watt resistors if you want to experiment further. Boards just need RCAs plugged in for in and out and a 10v to 20v dc power supply. Mine run from an old laptop battery. You can specify balanced input and outputs if you prefer. Interestingly , there doesn't seem to be any decrease in quality and my system is picky. Mine are running from a StereoCoffee passive LDR preamp into a pair of Hypex amps connected as bi-amps driving a pair of DIT hybrid electrostatics. I have tried values of 200hZ to 500hZ but will settle around 450hZ because ESLs require a higher crossover point. I could never get bass performance with passives and a good passive crossover is expensive, especially if you want to experiment with different crossover points. Hope this helps point you in the right direction. Mine saved me heaps of money and improved bass performance greatly. I learned the expensive way that passive crossovers are an art form, not to be undertaken lightly. Cheers, Rob
  13. Hi. I have a pair of T-Zeros with a pair of Mini ESL panels and they have no problem loading our large lounge area which is about 5 metres by 15 metres. They are very fast and don't lag behind the main speakers because of the 6.5 inch cones. Positioning is critical to extract ultimate performance. Simple instructions are provided. Mine are running low level inputs but the speaker level inputs do sound better with coned speakers. Very pleased with mine. Cheers, Rob
  14. Yes, Chris is StereoCoffee. He has helped me with my questions and I'm sure will be happy to answer any questions you have. Cheers, Rob
