Some members expressed some interest in following along and reading the information and findings as we run through the high-end head unit shootout so I have started a thread here for it.
A little background...
I wanted to check out some of the highly regarded head units to see how they stack up against each other, and in an effort to select the one that I like the best for my personal vehicle. This is a difficult process though if you don't have the necessary units to compare side by side, so myself and a couple of friends have pooled together and we are going to each bring some of the high end units to the table and do a day of comparisons, listening and measuring of the source units.
Thus far, we have the following on the list:
Panasonic CQ-TX5500 Bottlehead
These are widely considered some of the very top car audio source units ever created. Yes, there are a couple that aren't on the list (Alpine 7909, F1 Status come to mind) but these are the ones we have been able to procure. Testing probably won't happen for a couple weeks but we're getting closer.
My intent is to do the following:
-Measuring of output response for comparison
There are many of us on this site who enjoy reading subjective reviews for the fun and entertainment value as well as to hopefully give some things to think about. There are also plenty of us on the site who want to see objective data and don't give much weight to the subjective content. I'm hoping we can provide a little of both. I will state from the get-go however that your results may vary and I would encourage everyone to experiment, listen for yourselves and come to your own conclusions.
We will be using the analog output from each unit. We will use cd's as the source for listening testing and in the case of the Sony GS9 (which has no cd mechanism), I'll take the exact same music file source on the CD and put it on a usb stick to supply the Sony.
As for measurements, I'd like to feed signal into aux inputs and measure output with my software, but if that is not possible, then I will measure using a burned cd (and same file on the Sony GS9) to give a look at a comparative response. I'm a hobbyist and not professional- I'll do the best I can with the tools available.
