Earthquake Sound Cinenova Grande Multi-Channel Power Amplifier with Class A Bias

earthquake-cinenova-amplifier-teaser

We reviewed the Earthquake Sound Cinénova Grande multi-channel amplifier several years ago, but it has gone through some changes in the circuitry, including significantly higher output, so we thought it was time to revisit this legendary product. It is available with up to seven amplifier modules, each capable of delivering 360 watts RMS into 8 ohms. Our review unit came with five modules.

Bryston 3B SST2 Stereo 150 Watt per Channel Power Amplifier

bryston-3b-sst2-power-amplifier-teaser

Following on our review of the Bryston 14B SST2 stereo power amplifier, we now take a look at its smaller brother, the 3B SST2, which delivers 150 watts rms x 2 into 8 ohms. Although it won't necessarily rattle the wall studs like the 14B can, it provides good solid power at very low distortion.

Mystere pa21 Stereo Tube Power Amplifier

mystere-pa-21-power-amplifier-teaser

Durob Audio is a company in the Netherlands that markets PrimaLuna tubed audio components, including integrated amplifiers, power amplifiers, and a CD player that has a tube-based clock. It also has a discrete output stage with triodes running in pure Class A. Conventional CD players use op-amps in the output stage. Although the tube output stage and op-amp output stage sound different, one doesn't necessarily sound "better" than the other, although tubeophiles would all opt for the "better". We reviewed the PrimaLuna DiaLogue Two integrated amplifier in December, 2009.

With the introduction of Durob Audio's Mysterè line, we now review the Mysterè pa21, which is a 55 watt per channel stereo tube power amplifier. The Mysterè line goes beyond the PrimaLuna line with larger transformers, more power supply capacitance, and an auto-bias circuit that lets the consumer choose between using KT88's or EL34's as the output tubes.

Lindemann 882 Stereo Integrated Amplifier

Lindemann 882 Integrated Amplifier

I have always been a fan of integrated amplifiers, and they were the heart of all my audio systems up until recently. They offer the best value in terms of getting the most performance per dollar, but they take away one thing many audiophiles love: fooling around with their system. Several ultra-high end companies have recently introduced very serious integrated amps, for the audiophile who is done with fooling around.

Emotiva UPA-5 Five-Channel Power Amplifier

emotiva-upa-5-power-amplifier-teaser

Over the past decade, a lot has changed on receivers that we buy for home. We've gone from S-Video to Component to HDMI for video, replaced 6 RCA cables for 5.1 audio with a single digital cable, to having it integrated in the HDMI signal along with video. Receivers have added all sorts of new functions with better on screen menus, room correction, Ethernet ports for streaming media and firmware upgrades, and we have also moved from 5.1 channel audio, to 6.1, then 7.1, and now all the way to 9.1 or greater when using Dolby ProLogic IIz or Audyssey DSX. However, one thing on receivers has barely changed when I look back over the spec sheets: weight.
