I love Pacific, now with new engine to make it PAC 2. What is very fascinating feature for me, and I never thought that this feature will make it interesting, is the tube rolling. I could not believe when I replaced 6cN7 with double E83F($30) with Takacz adapter what sound was coming out, so much more resolution and transparency, and that is just one tube replaced, now there are other tubes 242,45, PX25 etc and their equivalents/alternatives from many producers, then the front tube 5u4G, 274b or 5c3s, endless combination to play with. Eacch combination sounds diffrent and not just by little. Most human beings in modern society get used to great life and get bored quickly and want something better, little latter they realize that better may not be actualy better and want to return something they abadonded in the past, same thing is happening in audio, here when you want change you got it, just replace one or 2 tubes( does not cost fortune) and you have a different component and sound. This happened to me when I owned Mola Tambaqui, great dac, but was still the same, you could just play with digital cable, power cables or more costly replacements of your gear or speakers. Here you just replace tube for few dollars and you have your change. This is just incredible feature of Pacific. Pacific rules!
