I searched but haven't found a definitive answer yet. I'm selling my alpine 9887 and replacing it with a double din. Sq is most important and I need navigation. I've searched and it seems like the Alpine INA-W900BT and maybe the Clarion NX500 are decent candidates. I can spend up to $900, maybe I can save up a little more if the there is enough of a difference in SQ for a unit that cost a little more.

Thanks for your inputs.

The Clarion NX501 would be hard to beat. The NX501 has a simple interface that organizes common functions on 3 screens. Sound quality is something you can always count on with Clarion head units, and the build quality is top notch. Navigation is integrated into the NX501, you get the latest maps, and the software can be updated by a dealer. Retail is 799.99.

What do you mean by "sound quality"? What in a unit would you say affects SQ? Just curious so I can help you ;)

S/N ratio & preout voltage

S/N ratio to compare between manufactures are useless because they are not standardize. Did they play at 100% (highest S/N ratio) or 50% (lower S/N ratio)

How does high pre-out voltage relate to the sound quality a unit is capable of? It is only useful in gain structure to match with amplifiers input voltage, higher is better IMO but nothing to say how well a unit will sound

in some cases (not all), higher preout voltages are better because there is less noise

Really?!?!? Is the noise from the head unit or by the amp with a turned up gain to compensate for the lower input voltage?

DAC, transport, laser pickup.

The problem is that manufacturers do not give insight to any of these, especially in the double-din navi market. We are not talking about Nakamichi, Denon, SoundMonitor, or high-end mainstream units Pioneer (Stage 4, ODR) or Alpine (F1 Status). Only way to really get this info would be to talk to a tech or get a hold of the repair manuals.

Just stating the facts and questioning questionable statements :)

So what headunit would you recommend with the available information available to the consumers (and/or based on your experience) that has a price point around $1k or less?

I bought the Kenwood DNX9960 for $979 (authorized dealer, closeout price), I know you can get them cheaper from Amazon/Ebay. It had EVERYTHING you could want in one package. Garmin Nav, Parrot BT, and Kenwood audio all in one unit. The issue was/is a slow processor and/or low cache/memory caused it to be slow to respond to user input while loading album art for the song that's loaded (about a 5 sec delay before it would respond). Very bad when the kids are in the car, and it's a parental advisory track! After complaints to my dealer, I got a deal on the DNX9980HD. Kenwood has a mail in rebate of 300 on the unit, and the dealer gave me 100 off the retail. So, I paid about 400 more to get the new unit. Now I know firmware updates will be released to cure lingering woes, because I have the new model as I am sure support will trial off for the 9960 soon. Oh, and these have two year warranties when purchased from an authorized dealer.

Kenwood, Clarion nx501, or ???
I'm looking to purchasing one really soon. Let's get some more personal experiences posted.

for over all audio options its hard to beat the kenwood double dins

and they have garmin nav also

i have a dnx-8120 from 2008 and the unit still sounds great

When you say sq I feel like you may want time alignment and the ability to run an active front stage, am I assuming to much?

I'm not ready to do an active setup yet, so it's not needed. Just a passive set of HSK165, with a pair of McIntosh amps and a IDMax10. A local shop is offering a DNX6980 for a pretty good price. I think I'm going to pull the trigger on that unit.

IMHO on the subject of SQ in relation to a head unit, if you're serious about it you'll want something that gives you all the tune-ability you need in one unit to make the most of your setup possible without requiring an outboard processor. Genuine SQ units tend to be devoid of the 'flash and pizazz' features designed to attract the Best Buy crowd. They won't have Bluetooth/DVD/SATNAV/SIRIUS/HD Radio/backup cam/custom screen saver all in one, and the best ones are actually single DIN. If you just want to design a CD player with superier sound processing capabilities, single din is enough space to package everything you need to make it great. If you want to design as much fluff as possible into a head unit, double din is the preferred starting point.

I find even at the 1000 dollar pricepoint in the double dins you're mostly paying for convenience and pizazz features, not SQ. At the level and pricepoint that most people are shopping, if you already have a good system to match it with, there won't be enough of a difference that it's worth concentrating on things like voltage and signal to noise ratio. It's more worth your while to get something with some decent tuning features that has the convenience features you're looking for, such as NAV or BT, then go with high quality components and install for the rest of the system. Out of the higher end end double dins, I like the Pioneers for the best compromise between offering mainstream pizazz with some decent adjustability.

This would include the 3300BT, 4300DVD, and the 8000BT for those that can do without NAV and touch screen. All offer 3 sets of 4 volt pre-outs, decent equalizers, and the stuff everybody wants now such as bluetooth and IPOD control. For pure SQ, none of them will surpass the head unit giving up. I don't know of anything in the double-din category that will match something like a 9887 for SQ.
