Aesthetix is a brand I sold for years and still has outstanding integrity ,they
wind their own transformers and enclose them in a faraday type cage to contain any magnetic fields , they build a quality product
even their integrated Mimas has a Hybrid Vacuum tube preamp section .
Coda too has Some nice products in their upper line ,who btw we’re Pass labs engineers before Pass went independant.
your speakers are what model and effficiency ? Very important to know.
i have 40+ years building system synergy .I owned $6 figure Audio systems
but technologies have moved on even class D look at AAvic from
Audio group Denmark ,they have great newer technologies ,in part using multiples
of Tesla coils to dramatically lower noise floor and many other things .
I myself am looking to upgrade but not until our home additions are completed
being married means Audio is not 1st ,since I no longer own a Audio store .
