Circle Labs A200 is a great tube front end with SS output hybrid integrated amp. Wonderful tonal purity! This is one to consider if comfortable with a smaller company located in Poland.
John Tucker of eXemplar Audio also makes a great sounding hybrid integrated amp. He lives in TN now and hand makes each one. Nice tube preamp section with SOTA voltage regulation on both the preamp and amplifier portions of the amp. Completely separated power supplies and trannys for both preamp and amplifier sections. Top quality parts throughout. His website is dated, but the contact info is still accurate. I own one and think it is very special. $5500 new. This is a steal folks.
There are other hybrid integrated amps with tube preamp sections from folks like Vincent Audio, Modwright, Unison Audio, Pathos, used Blue Circle Audio. Based on my experience you can spent a lot more for some of these and they won’t sound as good as the eXemplar.
