"Fuses are ½ (500mA) amp slow blow fuses.
I'm encouraged that they seem eager to assist which will go a long way in my future audio component decision making.
Thanks for the response and please, do not bother opening your ZPre2 preamps!
One thing I have yet to understand is the DAC, I've never experienced the difference having one adds to the overall process, I've read that it provides a more clean signal which translates into a cleaner end product being what ultimately reaches your ears but there's such a broad spectrum of choices and prices, seems the age old "you get what you pay for" would apply as well. Assembling an all "Z" product line would mean a strong consideration for the ZDac. preferably the v.2. At $279-$399 it might be out of reach for now, but certainly not out of the question. Just wondering if it would make that much of a difference?
Music for me is inspiring where the right song or tune can change my mood for the better, ever have a bad day, or just a bad moment where you're maybe discouraged, or bored, or just plain blah and you hear a new song, or an old favorite and before you know it you've forgotten about the blues? <--(inserted music pun fully intended) This experience (for me) is even more rich when the sound reproduction is superior. I suspect I'm in good company in this forum when it comes to high quality sound reproduction.
