Bi-wiring

 

I had always bi-wired my two way Transmission line speakers.  I broke the 'rules' on two counts with both unequal lengths and also differing brands on both drivers!!

 

Used Naim NAC5 on Bass and Absoilute Wire Force 4 on tweeter.

 

However, replacing them was quite tricky. I tried various screened/unscreened single wire/bi-wire options from Chord and Atlas and none sounded right, improved here or there but not overall.

 

Eventually tried a pair of Clearer Audio Silver line cables, expensive, but finally they sounded right and better in every department, so had a further unequal set made which I sit with today. 

 

The 4 core enables single (with jumper) or bi-wiring and in answer to the original question settled with the bi-wire option.

 

More recently I experiemented with plugs.

 

OE WBT Cu Banana & spades.  I had the opportunity to replace the spades with same Bananas and a suprsing improvement which ever way round, the spades boosting either driver and reducing clarify/deinition etc.  I decided to go with another set of Bananas.  Then another however sets in:

 

Decided to try the WBT silver bananas.  Quite how a silver plug can take time to burn in don't ask but from an initial overbright/forward/bass light presentation (albeit open and great clarity) after a 100 hours+ the result was great removing the brightness bringing a very even balance with unsually better calrity, soundstage etc.  I upgraded both amp termination and second speaker terminal to the same and the same pre-run in brightness existed but once all three sets in place they were extremely well balanced.  The exercise has been an expensive one (ebay good for clawing back the 3x Cu sets!) but this has been perhaps my most unexpected improvement which again appeared to defy any real logic,.  the previous recomendation from the supplier was of his preference for Spades over Bananas!

 

My conclusion is that you need to be open minded, believe your own ears, allow for lengthy burn ins (silver in particular) oh and a bit of spare cash doesn't always go amiss!
