Classé Sigma SSP, Sigma Amp2 and Sigma Amp5 Review

Travis Allanson

The Sigma SSP is Classé's newest 7.1 channel surround sound processor. Classé optimized it for two-channel music playback and gave it extensive customization features. Included in this review are the Classé Sigma Amp2 two-channel amplifier and Sigma Amp5 five-channel amplifier. The combination of the Sigma SSP, Amp2 and Amp5 produces exceptional sound quality for both music and movies.

Classe SSP-800 Surround Sound Processor

John E. Johnson, Jr.

Classé is considered one of the finest audio product manufacturers in North America. They market preamplifiers, power amplifiers, and surround sound processors (SSPs). The SSP-800 is their current processor. It's been around for awhile, and they have no plans to replace it with a new model in the near future, but there have been some firmware updates along the way. So, I decided that Secrets should have a look and listen to what I was sure would be a fine product. Was I right?

Integrating High-End Two-Channel Audio into Home Theater without Compromise

John E. Johnson, Jr.

For those of us who enjoy two-channel (stereo) audio using a high-end system, but also like our home theater with surround sound, how to integrate the two setups without compromising the stereo high-end system has been a conundrum. In this article, I will show you how to have both systems interconnected, but not compromise the sound when you want to listen to your stereo CDs, or SACD in stereo.

Classe CP-800 Stereo Preamplifier

John E. Johnson, Jr.

Classé's new CP-800 is a high performance ("High-End") stereo preamplifier, but it is not just yet another preamp with minor changes from previous models. This one has the option of switching in some DSP that adds several EQ bands and dedicated stereo subwoofer outputs. If you don't use the DSP, it's not in the signal path, and you can still call yourself a "purist" audiophile. Have no doubts; this is a very unique product, and the performance is stellar.

Classe CA-M600 Monoblock Power Amplifier

John E. Johnson, Jr.

Classé updated their Delta power amplifier series in late 2010, including the CA-M400 which is now the CA-M600. The entire amplification signal passes on a single circuit board, and they have introduced a new cooling system called ICTunnel™, which utilizes a fan on the inside front panel of the amplifier that draws aire into the chassis and over some fins that absorb heat fromt the circuit boards. In use, I found the fan to be whisper quiet, with just a gentle breeze coming from the front amplifier port. This kept the entire chassis cool, but also, the temperature of the circuit board is electronically controlled by adjusting the fan speed, to optimize the performance, which turned out to be stellar.

Classe CDP-502 DVD Player

Adrian Wittenberg

For a player as expensive as it is, the Classé CDP-502 could stand for some improvement in its core video performance.  Its de-interlacer performance is very good though, and the National Semiconductor AVC 2510 chip set handles most material very well, as there were really only a few minor hiccups it experienced in our DVD Player Benchmark™ tests. It would be hard for me to recommend this DVD player based on its video performance alone, but people in the market for a player in this price class will undoubtedly be looking at it for its ultra high-end audio performance. That, combined with a robust video feature set and the ability to up-convert any material to various HD resolutions through HDMI, makes the CDP-502 an impressive offering overall.
