Summary: I bought my first DEX-P99RS used from a giant online auction site last year. It was to spend it's life in a garage-queen SQ car that I occasionally show. I run a 2-way active Focal KRX2 set up-front in that car with Rockford Fosgate T1692 6x9's in the rear. I have 2 x JL Audio 13w6v2's for subs.
Pros: Left & Right 31 band EQ's.
Full Time Alignment (all 8 channels).
Good AutoEQ results.
Good AutoTA function.
Great CD mechanism.
Great iPod interface.
Highly customizeable (display, colors, sound, etc).
Very classy design.
Cons: It's more expensive than a decent double din + external DSP.
You can get a similar experience in AutoEQ and AutoTA with one of Pioneer's lower line double din units (AVH-X1700 - AVH-X5700BHS units). I had an AVH-X5700BHS prior.
Summary: this deck is by far the best deck i ever used . it takes a while to figure out the set up areas but customer service is a big help . this replaced my eclipse 8053 and it made my old deck seem lke it was a factory head unit .
Pros: best deck ever , one crossovers were set the cds took on a new life even before setting the eq and time delay
Cons: set up takes a learning curve and remote is hard to use if you have large hands . price
Summary: It's getting harder to find pre amp only head units these day. That's what brought me to the Pioneer. I was impressed with the build quality and the sound quality was top shelf. You get a ton of customizable settings.
Pros: Sound quality
Plenty of custom settings and flexibility
Cons: It would be nice if the head unit had a digital input and balanced line outputs.
Summary: I thought the last 10 + years of of high end head units were pretty much a lost cause since everything has become tailored for iPod quality sound, which as we know isn't nearly as good as complacent disc. This prs 99 is an outstanding piece of engineering and for me to say that means a lot.
Pros: Old school quality with faculty for modern day tech like iPhones and such.
Cons: Would like it to be able to play high resolution audio such as FLAC or ALAC 24/192 kHz files burned to a dvd or play sacd discs.
Summary: I believe that this is a difficult unit to understand. I took over one year to appriecate the built in quality of this CD player. Oneday i thought I finally had it tuned in and not evan close.
Pros: It can provide the best sound out there. Or it can take and break your spirit.
Summary: I have been waiting for this type of receiver for ever.The Last time I seen a preamp receiver was in the 80's was a Kenwood cassette receiver it was top of line, Now in the twenty teens we have once again simply the best sound, all I care about is the best sound possible period.
Pros: The best sound Quality in a CD receiver. no bells and whistles, just pure SQ.
