    Tube Pre-Amp or Tube Amplifier

    I'm a little hazy on this and the answer is probably self-evident. Question one: Which is more important to sound: A tube Pre Amp? or a Tube Amplifier? Question two: If the Amplifier is more important, can a SS pre amp feed into a tubed amp and will the results be similar or better? Or will...

    Aikido 12Vac line stage/pre-amp build & review

    Stay tuned. I just placed my order. I’ve got a Little Bear 6j1 pre in my system currently that is adequate but not quite doing it for me. I’ve also got a Douk 6p6p + 6j4, but it has way too much gain. Another AKer was kind enough to rework the schematic for me to make it more useable, and I...

    Mcintosh DA1 module

    I notice the only mcintosh products with the DA1 module are integrated amps that came out approximately 2017... are there any rumors/plans for these to be put into future preamplifiers? The current preamps I'm looking at came out in 2015, so I'm wondering what the future might hold! Thanks!

    Lowering tube preamp gain?

    I’m starting my journey into tube audio. Reading about design and theory when I have downtime but I haven’t gotten far. Built an ear834p clone that came out quite well.
