Yes you should definitely do that it will be much much better.
To upgrade from Simaudio 600I to 740p/860a combo?
Again, I ponder whether I should take the plunge and upgrade from the current Simaudio 600i integrated amp (125watts in 8ohm) to the Simaudio 740p/860a separate combo (200watts in 8ohms). How much money would I be out, well about 16,000. First question, do I need it? Currently own Franco Serblin Ketema (4ohm) speakers which appears to like a little more power than the 600i can put out. Will the modest upgrade to 200watt separate combo be beneficial. Thoughts from those that have listened to both the 600i and the 740p/860a combo.
