Judging from the description, it looks like a parametric eq to me. However, do correct me if Im wrong ok?

I don't think the sony HU got a parametic EQ. What I would do when shopping for a HU would be to hunt down the user manual online. From there normally you can see what the HU is really offering. You know la... the website normally is used for marketing ma... same feature between different brand, just use different 'fancy' names :_:
peace :shades_smile:

I would rather say that the Sony seemed like a much more better deal in terms of the features, even if you need to add additional amplifiers, there's no need for an additional pre-amp as it already has 3 pre-outs compared to only a single pre-out on the Alpine, and it has 24-bit DAC which IMO sounds more detail than a regular 1-bit DAC, but of coz, it's personal preference as i don't have scientific proof to back that up. The only downside i see is that the Alpine *might* be having a parametric EQ but not too sure about the Sony as it only says 3 Band EQ.

 

[cacin]

referring to the sony I have, the 3band eq (EQ3) is just a normal 3 band graphic EQ. Something like low, mid and high. The thing is, I don't know what frequency it is boosting or cutting. :emoticon_U:

The plus point that i want to say on the sony is the DSO. It raises the soundstage if you only have coaxial speakers on your doors. If you have a component set, well, I can say that you might not need this feature.

any reason why you are only looking at these 2 HU? At this price range, any HU comes with better feature?

alcon06 and cacin, u two are god to me, thankyou very much, as alcon06, i am not consider about brand thing, and yes to buy a HU is very easy, but to buy with knowing with HU u need is really not easy... man, but seems it is both branded, i will more see on feature that it's give and the quality of HU, not brand( but not un-randed one becos worry about quality)

Cacin, thanyou very much, u just say my unfamiliar and understand about the SOny' DSO, as i see this SOny interesting to me becos of its 24bit's, the DSO features, and 2 pre-out compare to basic sony model,

as say the SOny with add this 3 features is the CDA-350GT about rm550, compare with basic CDA-150GT, about rm 380, it is worth for about rm180 for the 24bits, DSO and etc??

as i am using component with amp at front door waja...that's mean DSO is no use for me aready...

i am also considering others brand HU, but does not have known about them..like sony DSO, Alpine bass engine.. i am looking around rm500-600, rm550 HU with perferable 24bits, atleast 2 preout, no need mp3 and vcd and looks..

apline is design for the sound of bass.
the sound should be more clear than sony.

for me i take alpine
coz alpine are expensive stuff
since both are same price, you paying alpine for quality and sony are for features.

so how many times did u guy touch ur HU features beside the P-EQ
we normall plug in the CD and listen
so i prefer to pay on quality not the fucntion

EG, for a a digital camera, expensive 1 with a lot of features like night mode, double effect, scenery mode, potrait mode, some i see got restaurant mode, outdoor mode, whateva mode
who will set their camera with those mode every time they take photo.
i guess most of us just use the Default mode (Program mode) and click the button onli
maybe certain time onli we use the special mode like nite mode. other are just the product selling point. tryin to sell more expensive with all the function which we don even use
right arrr?
