Following in the footsteps of the successful Glasshouse interconnect cable No. 1, we have created cable No. 2. Following a similar formula in the makeup of the 1st, but using Mundorf`s 99% silver / 1% gold 0.5mm single core wire, sheathed in PTFE.
The full interconnect kit is only £127.50 + vat + p&p. We use 3 strands of Mundorf`s wire, twisted together and wrapped in heatshrink, forming litz wire. For the best performance we use one wire for the signal and two for the earth. Its terminated with the superb Audio Note silver RCA plugs (CON-310, CON-311).
Being a kit, you are saving money as you are only purchasing the composite components, the mark up of these is a fraction of the mark up of a manufactured cable, plus you have the enjoyment of making a relatively simple kit (1 hours work). If you want us to make the cable up for you there is an extra £35.00 levy.
The cable needs about 100 hours to burn in. The cable is incredibly musical over the full frequency range, the highs are extremely detailed, mids are smooth, the bass is tight and controlled. Overall you will be amazed with the Glasshouse Interconnect Cable No. 2, so go on have a go, buy one today.
Instructions: Please refer to Pictures 2 & 3
- Cut three 1m lengths of the Mundorf silver/gold wire. Group together 3 ends, and hold 10mm of the wires in a vice, not too tight as to damage the wire, it is a good idea to line the mouth of the vice is wood, or a quick fix is to use cardboard.
- Pull the wire and at the other end trim the 3 wires so they are the same length. Wrap the end in a piece of masking tight and fit this into the mouth of a hand drill. Keep the tension up and make 10 revolutions of the drill. Remove the wires from the vice and the hand drill.
- Cut 94cm of the black heat shrink, thread the wire through. you should have 30mm of exposed wire at each end. Using a hot air gun, shrink the heatshrink. Note the heatshrink, once shrunk, will allow a little movement of the internal wire. Air is a great dielectric and this way there isn`t as much stress on the wire.
- Cut 6 x 40mm of heatshrink. Build up 3 layers at each end. Allow each layer of heatshrink to cool before putting on the next. Ensure that you still have 30mm of exposed wire showing at each end.
- Take one end and strip one of the wires. To strip the wire we have found the best method is to slightly squeeze the end with snipe nose pliers, lay the end on a cutting board and with a trimming knife (stanley knife) carefully cut along the length. You should be able to peel back the PTFE and cut off the excess.
- Expose 8mm of wire, bend the wire in half and tin with the Mundorf solder provided, this is the signal wire.
- Take the remaining 2 wires (earth) and cut back 15mm from the soldered tip of the signal. Expose 7mm of wire on both strands, twist together and tin with solder.
- Take one black RCA plug, familiarise yourself with how it is put together and separate all the parts. Thread the back portion onto the litz wire (correct way round).
- Tin the earth connection part internally, near the split, carefully use a vice of pliers to hold still while soldering. Solder the 2 joined earth wires to the earth connection part.
- Thread the signal wire through the earth connection part and into the signal post part and solder, wire in the opening.
- Fit all the RCA plug parts together and push the litz wire in slightly. Tightened the grub screw, but not too tight so as to penetrate the wires, you have now completed one termination.
- BEFORE you begin preparation of the other end you need to identify which of the three strands is the signal one. Using a multimeter set to DC resistance, hold one of the probes on the signal spigot of the finished RCA plug and with the other probe touch in turn the 3 strands until zero resistance is measured, this signifies the signal strand.
- Cut back the PTFE sleeving of this stand so as to expose 8mm of wire, bend the wire in half and tin with solder. You can now easily identify the signal portion.
- Take the remaining 2 unsoldered wires (earth) and cut back 15mm from the soldered tip of the signal strand.
- Expose 7mm of wire on both strands, twist together and tin with solder.
- Take the remaining black RCA plug, dismantle and thread the back portion onto the litz wire (correct way round).
- Tin the earth connection part internally, near the split and solder the earth wires to this point.
- Thread the signal wire through the earth connection part and the signal post part and solder at the opening.
- Fit all the RCA plug parts together and push the litz wire slightly up into the phono plug. Then tightened the grub screw, but not too tight so as to penetrate the wires, you have now completed both termination.
- Repeat the same process to create the red signal wire.
- The Mundorf wire is non-directional, however once the cable is in use, the crystals will align and the cable will sound better one way round rather than the other. Choose one end, take the "arrow" labels provided, some cellotape and fit the label near the phono plug so the arrow is pointing towards the phono plug it is close to. The arrow points in the direction from the source (CD player) to the Pre-amp or Intergrated amp.
