Audio Research D240 mkll vs Adcom GFA-555

Hey Folks, I currently have a modified Adcom GFA-555 but have the opportunity to purchase an Audio Research D240mkll. Will there be a significant increase in sound quality? Speakers are Sonus faber Chameleon B's and source is Tidal through a Project Pre Box S2 Digital (as preamp).

Thank you all for your thoughtful input. Everyone had great points and all were taken into consideration. The conclusion was I decided to take a much larger leap and purchase a Pass Labs XA-30.5 from someone here on AG (much to Erik_Squires chagrin I think). But I've enjoyed the modded Adcom and have been wanting to hear Nelson Pass's recent work and this was an opportunity to make that move. It's probably the only Pass amp I could ever afford but the reviews have been nothing but stellar. So thank you all again.

The D400 MKII which is a similar, higher power amp, can not be fixed by ARC if the PS caps need to be replaced due to age.

The D240 MKII does sound good after about 30 minutes of play.

But sounds poor during the first 3o minutes, even if left on continuously.

I think it is due to the odd ball, multiple emitter power transistors used.

Why buy an amp made in 1992?  There are better buys with more current power amps.
