Do I need a phono amp if I own an integrated amp?


I am new to vinyl and am learning the ins and outs of owning a high-end turntable. The most important question is: do I need a phono amp if I have an integrated amp? Can I just play the table off the integrated amp? Please answer.
Also, which is better for beginners, the Pro-ject Debut III or the Rega P2?
tstyes
The 'phono amp' is an RIAA equalization and step-up stage that must take place with phono cartridge signals. Many integrated amplifiers have this built in to them. Your instruction manual or the dealer should be able to verify this for you.
Depends on whether the integrated amp has an input specifically labeled "phono". If it does, then you have a phone preamp built in, and you do not need an outboard one.
Tstyes,
Looking at your system you appear to already own a Linn LP12 Sondek turntable. Also you're running seperates rather than an integrated, does your Kollector preamp have a phono input? If not then how are you running your turntable? Given the quality of the rest of your system, Linn CD12 and Klimax amps, I would think you would have some knowledge of the ins and outs of vinyl. I'm sorry to be so inquisitive, it's just you have the system of a seasoned "Linn-phile" while asking the questions of s true begginer.
If your intergated has a phono stage built in you will not need an external one as people have said.
I have one built in my Musical Fidelity A300.
I did add a dedicated phono stage later and it sounds much better than the built in one.
I added a Hagerman Cornet.
Buy a used phono stage if you get one.

Also, I might suggest a Technics SL -1200 turntable.
Some folks not crazy about direct drive, but I love mine and others think it competes with tables costing much more with some basic tonearm mods.

Good Luck.
Be careful with the phono input label. I know that there are models of E.A.R. integrated amps that have phono inputs, and a phono position on the source selector switch...but this is still just a line level input! I guess that they just did this for labeling convenience...but you will still need a phono pre-amp. I don't know if there are other manufactures who have done the same thing.
