First class - F5 / F5 turbo or F6 for tannoy 15 speakers


So nearly happy with whole setup - rega r8 or linn klimax DS into tron seven pre /then atc P1 into tannoy ardens

Problem with volume is I can hardly use more than first 1/4 so want something that works from late night listening levels up to about 90db at max for nearly all my listening. Only read good things about first watt but trying to decide between F5/F5 turbo and F6

Would love opinions if you know these amps

Someone has built one already and sells off his older build projects - the speakers are quite warm already so transparency and sound stage is more important to me

Details this 2 x 50Watt into 8 ohms Class A amplifier.
This is the nelson pass F5 turbo pure design
