Read thru this thread and didn't see this anywhere so I thought I'd add my 2c. Old tube amps like the Dynaco generally sound more "syrupy" and warm than good modern tube power amps like the Rogue CM. Old Dynacos, Conrad Johnson, Mac's, Scott's are wonderful for tube warmth but often have tubby bass but good midrange. If that is the sound signature in your mind then old or vintage is more likely your goal. I recently heard an upgraded Dynaco 35. I liked it a lot as I like the old tube sound. Same for a Scott 299c, great but low power. Heard a Rogue. Nice amp only sort of tubey to my ears. 8f you can, maybe try to audition some gear. Btw, I used an old Conrad Johnson pv10 tube preamp with various ss power amps for a couple of years. Got probably 80% of the tube magic for 2 years. Before that a pv5 was even more old school syrupy tube warmth. If your Yamaha allows for a pre that is a good option.
