I'm new to this..so pls bare with me ok..?

can anyone give me the complete command lines for 160-180 kbps VBR pls.. Can I get a perceptually identical copy from this setting or should I go for higher settings? If so.. can anyone give me the setting..?

Pls help

Search a bit and look here.

I already did..But they have just listed '--preset insane' '--preset standard' etc..
I need to paste the preset in EAC and start ripping...I can't do that without knowing the exact codings...

I'm currently using this Setting-
-V 2 --vbr-new --add-id3v2 --pad-id3v2 --ta "%a" --tt "%t" --tl "%g" --ty "%y" --tn "%n" %s %d

So All I need is coding like this to paste in EAC for the settings I asked..

Hope I was clear about my problem than before

The commandline you use will give you about 180-210 VBR. For lower bitrates, you have to adjust the "V" value, e.g.:
-V 3 --vbr-new --add-id3v2 --pad-id3v2 --ta "%a" --tt "%t" --tl "%g" --ty "%y" --tn "%n" %s %d
or
-V 4 --vbr-new --add-id3v2 --pad-id3v2 --ta "%a" --tt "%t" --tl "%g" --ty "%y" --tn "%n" %s %d

If you want "perceptually identical" which I suppose you are trying to say "I want transparent encodings that I can't tell the difference from the original CD" then you should use the List of recommended LAME settings in the link already giving, they're proven effective for archiving your music using proper settings that you don't have to tweak.

If the resulting bitrate of -V2 --vbrnew is too high for your needs (hearing capabilities) and since you strictly are wanting to be inbetween 160-180 kbps you can always try -V4 --vbrnew (old --preset fast medium), or -V3 --vbrnew which is inbetween (old --preset fast medium & --preset fast standard).

It's best to refer to the chart listed in the List of recommended LAME settings versus coming up with something on your own that most likely won't yield better quality. The chart will give you an approximation of the average bitrate, however depending upon the type of music you listen to the bitrate can and may bloat.

Therein lies the problem... what you percieve and what I percieve are two different things.
For you, 180 might be transparent, for someone else, 128 is transparent. For others, 320 still isn't good enough.
Then you've got environemntal issues... in the loungeroom, 320 might not be good enough, but on a train, 128 will probably seem transparent.
Take from all of that what you will!

Thanx for all the help guys..much appriciated..

I think the settings also depends on the kind of music you are ripping...If I am ripping metal music, think I'm gonna use a lower preset..If I'm ripping hip hop I'll use a higher setting..

And since I'm ripping metal, I'm gonna use a lower setting

I hope you mean "V level" and not bitrate. Metal generally requires a much higher bitrate than (most) hip hop.

For metal, I find -V2 --lowpass 16 will give you good results within the range you're asking for. Or if you want something that will encode a little quicker with not a whole lot of difference, then try -V2 --vbr-new -Y

(Metal has a lot of complex, high frequency content, which tends to bloat the bitrate. And you can't hear most of it anyway. So to bring the bitrate down, you remove some high frequency content. --lowpass 16 and -Y do this, in different ways.)
