Emotiva XPR-1 Monoblock Power Amplifier

Emotiva XPR-1 AmplifierAfter releasing a 500 watt monoblock power amplifier, the XPA-1, Emotiva didn't stop there. The newest addition to their monoblock power amplifier line is the XPR-1, which delivers 1,000 watts RMS into 8 Ohms. It may strain your back to move it, but it will set you back only $1,500.

Pass Labs XP-10 Stereo Preamplifier

 Pass XP-10In the past, we reviewed the Pass Labs XP-20 and XP-30 stereo preamplifiers. Now, we come full circle with a review of the remaining member of their preamplifier trio, the XP-10, which is the least expensive model. It is fully balanced, and has a slightly different sound character compared to the other two, which also sound different from one another. All three are great products, so you can choose based on price and/or sound characteristics.

NAD C 390DD Direct Digital Integrated Amplifier

NAD M3 Integrated Stereo Amplifier

If you look at the specs of most stereo integrated amplifiers, the rated RMS power output is between 60 watts and 120 watts per channel. This is lower than the power output of outboard power amplifiers, which typically are about 125 watts to 300 watts per channel. Monoblocks go all the way up to 2,000 watts output. One of the main reasons for this is that in an integrated power amplifier, the preamplifier circuit is situated very close to the power amplifier. Keeping the high voltage, high current power amplifier signal from inducting noise into the preamplifier circuit is difficult. NAD apparently has solved this problem with the introduction of their M3 Integrated Amplifier, which has a rated output of 180 watts per channel, at 0.004% THD+N, and clipping (1% THD+N) at 220 watts.

Anthem P2 Two-Channel Power Amplifier

Anthem P2 Two-Channel Power Amplifier

Anthem's statement multi-channel power amplifiers are called the P series. They come in two versions, a five-channel (P5) and a two-channel (P2). My home theater test lab has a 200 watt x 5 amplifier which works great for the majority of applications, but it is driving electrostatic speakers (ESLs), and for a handful of Blu-ray movies, the amplifier will go into protect mode when at high volume, because ESLs typically have a very low impedance (1 ohm) in the high frequency range.
