System advice

Haven’t been in forums in years. Previous audiophile that got burned out from audio fever of chasing the grail of audio nirvana. Previous system was Merlin VSM MXE with Ars sonum filharmonia with cardas golden ref cables. Interested in getting a quality 2 channel system. Requirement are full range speakers, integrated amp which can be tube or SS, and high end streaming device. No hard media will be used. I want this to be simple with fewer components/cables. Dac in amp or streaming device. Will be used in dedicated room that shares my HT. Will buy preowned from here. Typically listen to classical, jazz, crooners, acoustic. Budget 12-15k.
