I agree with a tube pre and SS amp.
I also agree with horn speakers. I have a pair of Volti that I enjoy with all types of music. JBL are nice, although never had opportunity to spend any length of time with them. I guy I know in my area has a set of Rethm Saadhana he is selling for a fair price on another audio site in the US. They are also very nice and I have often spent time listening to then in his system. I dont really ever see Volti on sale used, but a new pair of Rivals are only slightly above your price. Good luck on your journey
