I'm looking to get into tubes for a home 2 channel hi fi system. An amp I had for 30 years went out on me and in this next iteration I want to be able to both hear some of what I think is a "tube sound" as well as to have the fun of doing some tube rolling to play around with hearing how different tubes affect the overall experience. I'm relatively restricted by dollars, looking to spend only around $1500 for an amp/preamp be they separate or integrated. There are such an infinite number of options and equally many opinions, I realize. Here are a few things I was looking at. 1) Schiit - Valhalla (all tube headphone amp/preamp) --> Aegir (amp) >>>> Does anyone have thoughts or experience with using a headphone amp as a preamp for a traditional 2 channel system? 2) Willsenton R8 integrated amplifier 3) Boyuurange A50 MkIII (300B tubes, but only 6 watts per channel) I'm currently only running a small pair of Epos M5 bookshelf speakers, but I'm looking to find a used pair of Klipsch Fortes, Heresy, or similar in the near future. Does anyone have any thoughts, advice, or experience with these or similar pieces? Thank you in advance for our input.
