What tube amp for starting out?


I am confused of what amp(tube)I should consider as a step up from my ST-70(DYNACO),BROUGHT back to original with modern up to date parts.
I think the sound is very realistic but a bit dead in the mid range.
All other gear is also Dynaco....preamp,tuner.
I AM new to all the many choices now available and love music and want to listen to a presence of the most realism as possible.

I can also recommend the McIntosh MC275 series IV.
This is good to start out, and good all the way down the road. Well worth it!

Best,

Paul
I would second a used conrad-johnson MV-50, 52 or 55. It uses the same large tubes as your Dyna (6CA7/EL34/KT77)and puts out just a bit more power. They are very reliable and will be a big step up clarity, detail and dynamics. Used prices are in the $750.00 to $1200.00 range depending on model and condition.
