Krell 400xi wins hands down. Before faving purchased Krell integrated I had Primare I30 for two months. These are 3 major differences:
- Krell is able to drive evry kind of speaker if impedence don't fall below 2 ohms. Primare is much less powerful, a two-way mid-size floorstander Dynaudio Focus 220 is too diffcult for it.
- Krell offers very tight, fast, powerful bass. With Primare You have plenty of low bass but it's not so fast nor authoritative.
- the top end is fuller with Krell. But attention to marriage, if You match Krell with speakers that offer themselves too much highs, it may be a problem...
But Primare I30 is not a bad amplifier, especially for classical music.
