Does Luxman Still import tube gear to the US? I used to enjoy the rich full sound of their SS gear years a go when I owned a TOTL receiver. It's a matter of how you want to the sound to add up as it were.
Asa general recommendation I prefer the sound of octal pre tubes like 6SN7s there are a number of pre amps around that you may want to investigate. Maple Tree audio custom builds such pre amps.
Atmasphere also builds -a unique to him- line of such pre amps configurable to your needs.
Both in your price point- as usual no financial affiliation whatsoever
