I certainly have no plans to replace my Napalm, as I'm more than happy with it.
Yeah, I had a "regular" Bolder digital beforehand that I was using. It was outfitted with Silver Bullets & was cryo treated.
And my Napalm is also cryo treated, but it actually has 2 Bybees in it.
My Napalm was easily cleaner & more life-like with virtually no noise floor. It actually took me a day or two to get used to the complete lack of noise in the signal w/the Napalm. I was very happy with my regular Bolder digitals in the first place, but the Napalm is definitely better.
I also had the chance to briefly compare my Napalm to a silver bullet cryo'd Bolder w/Bybee inline adapter to my Napalm. The Napalm was a bit better. I didn't have much time to go back & forth, so I can't give you very specific details on what was better. Maybe Wayne can recall that better as he was the only other person there, and obviously knows his setup better than I do.
And I've had the opportunity to compare my Napalm with a Transparent Audio Reference AES/EBU digital ($1,200). They were damn close. But the Napalm sounded a bit less harsh in vocals & a bit more life-like than the Transparent. So I was happy that my Napalm not only stood up to a much more expensive digital, but was even a bit better...
I currently use 3 digitals in my setup. 2 are regular Silver bullet cryo'd Bolders, the other is the Cryo'd Napalm Ultra. And when I have the extra $ to do it, I'll replace the standard cables with Napalm's.
