Tube Research Labs Solid State Designs

Bluemike,
Again, I owned the Audiopax 88's at a time when I did not have the TRl and they are so different it is hard to compare.
I think the Audiopax are wonderful with the right speaker...one of the most natural and musical amps I have had the pleasure of using.
The TRL is more versatile and mine (ST 225) has the benefit of being an integrated so again on the value scale it is not close.
It's really probably a Chocolate/Vanilla thing with these.
The TRL has a more dynamic, vivid and forward presentation where the Audiopax has more of an organic and liquid quality.
Both are musical and your preference would most likely lie with associated equipment (synergy) and personal taste.

I have the ST 225 from TRL which is the integrated.
It is excellent and for the $$ is an excellent value.

Bluemike,
I have not had the chance to compare the two directly so will rely on memory.
I replaced the stellavox with the goldmund 18.4 monos and felt they (18.4's) were better in every parameter...except price (the stella's, like the TRL, are value champs imho)

I think the quality of sound with the trl and the 18.4's are very similar...quiet, fast, dynamic, neutral, powerful.

The goldmund fit and finish was superb where the trl is ok.. by high end standards

The trl is 30% the cost of the goldmund so on the value scale the trl is the clear winner.

I am using the Dartzeel now and like it better than the trl but again on the value scale there is no comparison.

Bluemike,
I enjoyed the Tonian TLM's for quite awhile and if your Tonians are close I would lean hard toward the TRL with these. I know thier sensitivity cries for tubes...and they sound quite good with many tube amps...but I think the TRL (at least with the TLM-1's) will give you more.

I had the Audiopax when Tony delivered my speakers and when we took the Audiopax out and put the stellavox in the speakers really came to life.

Bluemike,
I go straight to the wall and dedicated outlets with my power amp(s).
