If you just want to try out tubes I suggest you start with a simple tube buffer.About $150.00 opposed to $1000.00..Hybrids are a pretty good compromise but IMO with all the excellent choices in an all tube integrated amp from Yaqin,Cayin and many others why dip a toe when you can dive right in?

This looks like a good integrated to get one’s feet wet and try out vacuum tube sound. On sale.
