Our Take
If you thought Rotel produced great CD & amplifier products in the under three grand range then you'd be correct. But you're be missing out on the bigger picture, because Rotel's Michi range offers serious high end amplification with impressive specifications, build quality and handsome good looks.
The Michi X3 Series 2, almost unbelievably, is their entry level model! Most other brands would call it a flagship. It 'only' has 200 Watts into 8 Ohms, whereas its bigger brother, the X5, has a massive 350 Watts. However, even speakers rated at 8 Ohms often have dips in their impedance at certain frequencies down to 3 or 4 Ohms (just have a look at the B&W 700 S3 range – which the X3 Series 2 sounds great with, by the way). This means the X3 Series 2 gets to stretch its legs and wind out to 350 Watts into 4 Ohms and even more as the impedance gets lower. Hi-Fi News put the X3 Series 2 on the test bench and these were the results. "The X3 Series 2 measures 2 x 225W (8 Ohms) and 2 x 425W (4 Ohms) at <1% THD with sufficient headroom galvanised by that huge PSU to support 307W, 585W, 1.1kW and 1.78kW (42.1A) into 8, 4, 2 and 1 Ohm loads under dynamic conditions." So, we don't think you'll be running out of dynamic headroom anytime soon.
Balanced XLR & single ended RCA inputs are on offer as well as a moving magnet input begging for a good quality turntable hookup. Bi-Wiring is available through dual sets of Rhodium plated custom Michi speaker binding posts. Oh, and there's a whole cutting edge digital section that supports all the usual suspects including, optical, coaxial, USB-B (MQA & Roon compatible), Ethernet & Bluetooth aptX HD. So, it has all the connectivity and power you could possibly want but does it have the musical goods? Well, if you're looking for an effortless sound with embracing musicality, fine dynamics and beautiful tonal characteristics then this amplifier might be perfect for you. The X3 Series 2 is a lively, yet fluid conduit to the performers and has a real 'you are there' quality about it that can become quite addictive. As with the higher priced X5 Series 2, the same warning applies. Be careful, auditioning this amplifier might be harmful to your wallet.
