I am using Jadis JP200MC AND JA500 4 ohms. I think this is the best matching in my Mezzo Utopia system especially the mid range and bass is perfect. I don't think low watt or single end can control the bass. If you prefer low watt a smaller room may be accaptable.
Which amp matches best my JM Lab Mezzo Utopia ?
I have clearly a predisposition to single ended and Class A design. Push pull does not apply. The speakers are a demanding load though. They go down to 3.8 ohms.
