Andy 2 - Beetlemania and Holco (?) both reported improvements with internal wire. I have wire from StraightWire and Cardas in my comparison kit. However, the wire itself in the 2.4s is pretty high-end. It is 5-9s, high purity, low oxygen, long crystal, high polish 18 gauge solid in teflon jackets, precision twisted at 2.5 / inch. We first developed that wire in 1978 via our access to aerospace instrumentation solutions. The ITT aerospace 6-9s wire is no longer available, but current Thiel wire is as good as is available for its type.
Now, all that said, I believe there is possibly room for improvement via multi-gauge litzed bundling. Remember that a manufacturer occupying Thiel's cost-effective niche, can never afford state of the art, every decision is balanced for optimizing cost-effective balanced performance. But I will be substituting more sophisticated wire to compare its performance with stock.
I should note that in the development of the original 03 in 1977, wire purity for hookup and coils was paramount to getting listenable results from the phase coherent configuration, as I have elaborated earlier in this thread. I am very tuned in to wire, wire was in my purview during Thiel's first 20 years.
