Review: Rotel RC-1070 Preamplifier

Category: Preamps

Well this preamplifier was sort of my first taste of mid-fi audio. First off, the looks are definitely fashionable, but not knock your socks off gorgeous. Functionally, it is remote controlled and all knobs are solid and work reliably. Moving to the sound, it was pretty smooth and tubelike sounding. Midrange was smooth and revealing, definitely a good match for the B&W speakers. But the problem I found was that it did not seem to have good control with bass, which in part is due to the RB 1080 amplifier as well. But other than that, I was very impressed with the sound of the budget preamplifier. One mistake is playing two sources at once, the preamp does have a tendency to bleed from source to source, so this can be a problem, but not if you are aware of it. The total harmonic distortion was nearly non existent, it is an extremely quiet preamp. Compared to NAD material, I found the Rotel to be a better match for my B&W speakers. NAD seemed to be a little less revealing in the midrange, but just an overall decent performer. If I were to rate the RC 1070, I would definitely give it a 4 out of 5. It is no dropdead gorgeous preamp, but it is a good bang for buck piece of equipment.

If you are not satisfied with the bass performance, I tend to believe the blame is not with RB-1080 nor with B&W.
I would look at RC-1070 instead. It is nice, but not in the same league with the rest of your equipment.

Rotel RB-1080 has one of the highest damping factors of all power amps -1000 (!). Even if due to speaker connectors/cables damping factor drops tenfold to 100, your Rotel power amp is capable of competently handling even the most demanding speakers. To use authomobile analogy, it handles bass the way BMW 850 handles Alpine autobahn. Effortlessly. RB-1080 is a gem for the money.

Also, consider upgrading stock AC power cables on RB-1080 and FMJ to better one. Even $10 Volex 17604 or 17605 makes a signifficant audible difference. Mains filter such as Rotel RLC 900 ($100-120 used) for digital end and preamp can also make signifficant improvement.

Just my .002
