What speakers? I would say Cayin AT88 but with good, may be NOS 6550s not Chinese KT88s. One of my gear that I regret having sold, truly good sounding with the flexibility of triode-UL operations. No fake warmish tubish sound.
Don't know which amp is better, however check out this link:

Owner seem knowledgable, credible and most of all, previously had cav50 and replaced it with a Primaluna Prologue 2. In NO way am I saying Cayin A88T = PrimaLuna, however they are from same factory and kt88/el34 capable.
