**Q: Can the fosi t2 headphone amp work with the fosi Q5 dac**
A: Assuming you mean the p2 headphone amp, yes, it will. You'll need an RCA cable to connect the two.

**Q: Was everyone satisfied with the quality of the vacuum tubes provided? If not, what might be a worthwhile upgrade?**
A: I've sampled Brimar 5749's and GE 5654's and the ones that came with -- the differences are subtle (the tubes on this are only for the pre-amp stage) -- no complaints for the $50 price tag -- it's as good as any headphone amp I've tried under $150  and mine has been working perfect for over a year

**Q: With this fossi amp for headphones , would it be wise to get your dac converter ? i’m using a iphone as the sorce of music**
