Yes, the vintage amp has been thoroughly bench tested and repaired as needed. According to the stereophile's definition of clipping at 1% THD it actually hits 260ish WPC before clipping.

I have two amps that I have been testing back and forth to decide which to keep. The big vintage amp seems to sound more full and forward, deeper sound stage, and it has that oomph for sure. The new amp seems to be more detailed but a little reserved, not as deep a soundstage (but very wide) and I think it might have a little better bass control and definition at the expense of fullness. Struggling to decide between the two. Both go plenty loud!

Side note, could the Sierra LX hand the power of a McIntosh MC452? I have a deal that might fall into my lap but thats a huge amp and probably overkill.
