I tend to recognize more of a difference in preamps than amps in my setups. More detail specifically, maybe ’air’ as some define it.
I’m not doubting other’s opinions at all. But I know when I ended up with my first nice preamp, (nice to me) it changed my expectations regarding what was possible.
Much more refined and expensive gear than mine on here. In my case it was a preamp that retailed for around $2,500, but I really enjoy it.
