Interesting last few post's......
I found that the TWag cable with my JH16'si out stripped the stock cable it came with and when i sent my TWag back to Whiplash to change to balanced connector for the PB1 & DB1 I was about to purchase I had to reluctantly revert back to the stock cable during that time with my 16's for two weeks and was hard to enjoy as with the TWag cable and believe me i was glad to get the TWag cable back, was a long two weeks.
For me the TWag compared to the stock had more sense of space with improved sound staging, the stock felt more compressed, narrow and claustrophobic in this sense. Further more the TWag really made the high end a lot more sharper with sparkle that is more apparent and the low end really is tightened up, cleaner and more controlled but yet maintains that visceral bass the 16's are capable of at the same time which really helps in hearing the detail to be had in the over all listening experience.
Personally the whole system was only good as the weakest link in the chain, in this case the JH stock cable.
Maybe after spending circa 1.5K on the 16pros & the DB1 & PB1 another $275 was worth the extra investment/punt to make it sing even further which thankfully it does.
As for the Toucan i have now with the Boomslang the JH16's are now in heaven, going balanced is really another level to SE in conjunction with having a cable that is good enough to act as a signal train for the information from source in this case not the stock cable JH provide.
