Hi guys, I had originally bought an Onkyo 595 in December ($450 at Circuit City) and was quite happy with that receiver for a while... until I ran into the DD audio dropouts bug and encountered it in JP3, Pearl Harbor, and Atlantis. I decided to return the receiver in January, but in the end I came out with a deal where CC would upgrade the reciever to the newer model whenever it came out. Anyway, I picked up the new 600 on Friday and have been playing around with since then. There has been a lot of interest for this receiver in the forum lately and since reviews are hard to find, I decided to post my initial thoughts on the receiver. System Configuration: My system consists of JBL S312, S36, & S-Center speakers (no subwoofer yet, I'm in an apartment), Toshiba 32A40 TV, Hi-fi VCR (for the Star Wars and Indiana Jones Trilogies), DVD playback through S-Video and Digital Coaxial on the RealMagic Hollywood Plus Decoder Card on the PC, and audio input through my sound card for MP3's, etc... I also had my friend's PS2 and Gamecube hooked up through component video inputs on the Onkyo 600 for a while. Build Quality: The new model looks just as good as the older 595 and is aesthetically pleasing. The face-plate looks to be solidly built and has a simple understated layout for all the buttons. The dot-matrix screen is pretty big and is easy to see while sitting 7 feet away from the system. Bass and Treble knobs are no longer present and all adjustements are done through the OSD/Processor. All inputs are logically laid out on the back panel and are again very easy to figure out and use. However, I think Onkyo cut corners in some areas... The metal used to house the unit weighs less and seems to have a cheaper feel than the 595. The 600 also doesn't have binding posts for B Speaker outputs while the rest of the binding posts also seem to be made out of cheaper plastic than the ones used for the 595. Finally, the unit weighs in at 24.5 pounds which is slightly less than the 25.5 pounds of the 595. Thankfully, all this hasn't really affected the amplication and processing capabilities of the receiver. Connections and Setup: First off I found that the 600 was missing a few of features which were present in the older model. The 595 allowed you to set the startup volume (and the maximum volume) so that the receiver would always start at the level you wanted. The 595 also had a switch on the back panel to set the minimum impedence levels to either 4 ohms or 6 ohms. Both of these options are missing in the newer 600. In addition, the 600 has a 3/1 optical/coaxial digital audio input configuration rather than the 2/2 config on the 595. There is also no phono input, so those of you with a record player are out of luck unles you uby a phono preamp. However, the receiver makes up for all this by adding a lot of other cool features. It has an On-Screen Display (OSD) for setting up the unit and can be used on either the composite or S-Video outputs. Bass Management is still pretty simple, but the 600 supports crossing over speakers at 80 Hz, 100 Hz, and 120 Hz (the 595 only supported 80 Hz). Since I do not have a subwoofer, my JBL S312's automatically got set as Large and I set my surround and center speakers crossed over at 80 Hz. The OSD allows you set up default audio modes for each source input and also has an IntelliVolume feature which can adjust for volume differences between various sources. The 600 also adds full configuration options for DTS Neo:6 (Center Image) and DD Prologic II (Panorama, Dimension & Center Width). Finally, the 600 adds HDTV level (60Mhz) component switching capabilites. I don't have a HDTV, but I did try this out by hooking up my friend's PS2 and Gamecube and could find no degradation in signal quality. A/V inputs are also present on the front panel which were absent on the 595. Remote Control: Again, the newer receiver is missing a feature present on the older one (sigh!). The remote for the 595 could control upto 8 devices whereas the newer 600 remote only controls 6 devices (its missing support for Cable and Sat modes). Other than that, it is just the same (and good) as the one on the older 595. It is very intuitive and is incredible easy to use. Programming it to support other devices and setting up macros is done in a few moments. I basically just use the Onkyo Remote now instead of having 5 different remotes for the TV, VCR, Receiver, Hollywood Plus Decoder Card & the PS2. Processing and Amplification: There is nothing missing here, and this is where the 600 truly shines and outpaces the older 595. The 600 has full support for DD-EX (Matrix), DD-Prologic II (Movie and Music), DTS-ES (Matrix & Discrete), and DTS Neo:6 (Movie and Music) modes. The audio dropouts issue seems to be fixed (I tried out the Atlantis DVD) and the receiver can automatically detect the DD-EX flag. The EX mode can also be turned on for other DVD's where the flag isn't present (like Fight Club, Terminator 2, and the Phantom Menace). DTS-ES was also automatically detected on Gladiator (Discrete) and could be turned on for Terminator 2 (Matrix). Prologic II also sounded great with pretty good channel seperation (I tried it out on my widescreen VHS copies of Raiders of the Lost Ark and The Empire Strikes Back). I cannot comment on the 6.1 amplification completely since I only have 5 speakers hooked up for now, but the movies I tried out (Atlantis, Fight Club, Terminator 2, Gladiator, & the Phantom Menace) sounded great. I found surpisingly more clarity than what I had heard previously on the 595 and could even pick out subtle effects with ease. The receiver also seems to have much more headroom in the amplification than the 595, and I could play it much louder than before while maintaining the clarity. It drove my full range S312 (12 inch woofers) very well and I couldn't really feel the lack of a subwoofer in the system. However, I am in an apartment with a small living room, so those with larger rooms/houses would probably want a sub. Final Thoughts: Overall, inspite of some missing features, I am very happy with the upgrade that I got with the 600 over the 595. I am already thinking of upgrading again (this never ends )and getting a 6th speaker to try out the 6.1 capabilites. Having preouts would almost make this a perfect receiver, but already its a great receiver for the $450 that I paid for it. Anyway, I'll be happy to answer any questions that you guys have. Parin PS: This post wound up to be much longer than I expected... I'm sorry it gets too tedious .
