@georgehifi I agree with your assessment of impedance mismatch between the Hattor passive (unbuffered) preamp and the choices of amplifiers that tweak1 selected.
@tweak1 You initiated this thread discussing passive preamps, yet you have nearly changed everything downstream to accommodate it (that is, the Hattor passive unbuffered preamp). This includes a new amp, a different set of speakers and ditching your powered subs. I respectfully disagree with your assessment that a simple gain switch will rectify the impedance mismatch George referred to. Just for kicks, why not obtain his suggested amp to audition? You’ve changed so much already; one more audition won’t be much work. And don’t be afraid to liberate yourself from the need of a class D amp, unless you are worried about electric bills. There are a lot of good design topologies that will likely bring smiles to your face when mated into your system.
Trying is the pudding of life. And I know you at least enjoy trying new gear!
Just my two cents!! Enjoy the music!!
