Tube amp comparison

Let me add, any of these can sound totally different if they had new coupling caps, or mods done.

I own a Dynaco ST-70, I have owned a McIntosh MC 30 and I have heard the Marantz 8b. The marantz sounded the best to me. The Dynaco was the cheapest of the 3 but still sounds decent. shay

Agree with above and favor the 8b. I bought one for nostalgia to go with my 10b and 7c. I wasn't expecting much but got a real pleasant surprise using it to drive some Sonus Faber Guarneris. I like being able to roll the el34's and bias each one individually.

Heard Will Vincent's Dyna 70 triode mod (22WPC) recently at a friend's house. Sounded fabulous.

It would be hard to compare those totally different(Dynaco named) amps to a Stereo 70. There is one for sale now that has different output transformers on it. Definitely not a Stereo 70 tranny. The others that are painted would be hard or impossible to tell what time frame they were from, as the company went through several different changes on in house made parts, to having them made for them outputs, and other parts. They look nice, and may sound nice, but everyone may have a different version. The one that's for sale now(with those outputs) could never be made to sound like the original.Nice looking though.
