I can see why it would make a great ortho amp because its strengths of great mids and mild bass matches the typical sound signature of orthos.
Thanks for your impressions on my previous amp. It will remain my reference amp for the foreseeable future though I don't have it with me anymore. I would say that the bass on the stacker is deep, extended and as tight as they come. It does this better than any of the amps I have built or heard. However, they don't have the bass impact that the EHHA of my Liquid Gold amps have simply cause I believe for the lower output current capabilities when compared to the other two. But bass definition is by far the best on the stacker 2. One other reason why i think the bass might have felt light is that the DAC that I sold along with that amp has a lighter presentation in that frequency region compared to the identical DAC that I have here with me.
However, if the bass impact can be improved by rolling the output transistors to the other pair of Toshibas i tried without digressing at all from the current sound signature.
Did anyone listen to the LCD-2 on this combo?
