Dynaco ST 70 ohm question

[KCguy33]

I recently read a thread where another user asked how to connect the speakers to his Dynaco ST 70. One response suggested that he connect his 8 ohm speakers to the 4 ohm post, and doing that would result in the best sound. Is this true?

I have a pair of Altec 604E's, which are 16 ohms, so I have them connected to the 16 ohm post. Should I switch the connection for "better" sound? Thanks!!

La Scalas on the 8 ohm tap here.

Try them all - whichever you like best is the best.

The maximun power transfer will happen with the 16 ohm tap , the damping factor will change using the other taps

No.

Yes matching the speaker LOAD to the appropriate tap is the best place to "start".

Try them all and see what sounds best to you, if an amp was designed to provide
the best load to the output tubes with a speaker matched to it's appropriate tap
then that will be the best "technical" connection, but it may not sound the best.

Also output transformers that have multiple taps, connecting to the highest one is
generally using ALL of the secondary winding an technically better then the others.
(having 16ohm speaker on the highest(16ohm) tap can be quite a good thing to do)
