Do i need an amp along with a receiver?

[Craft23]

I have some polk audio tower speakers and am looking to by a receiver and sub. I am looking at thee Denon X2100W for a receiver and am wondering if I buy that do I also need to buy an amp for the sub?

Also, whatever the answer is how would I know, what details or specs should I be looking at for the answer? Thanks

Most commercially sold subs are active and they have their own amp. Unless you get (pretty rare) commercial passive sub or go DIY - no need to buy amp for sub.

Keep in mind that speakers (including sub) make up to 95% of total sound quality. Electronics as long as they are operating within their range are not that important. difference between 100watt and 120w is very tiny in practise. Features are more important to learn and know what is relevant to you.

People say - don't try to future proof and they are right to a point. I still have my old Onkyo TX-SR805 reciever which handles my tv, sources and speakers nicely. I don't miss 3D or 4k, but I wish I had more modern version of Audyssey. But then I bought it - it had all the latest features available at the time.

Ok that makes sense, I'm totally new to all this stuff but I do know about Audyssey which I will be getting but other than that I dont really know any features I want other than bluetooth. Are there any features you would suggest that I should look into?

one feature which manufactures tend to keep away from low and low-mid tiers is multichannel pre-outs - these allow you in future to use avr as pre-pro and use external amps.
With some very hard to power speakers - this would be huge deal, but for more speakers - it's non an issue. The problem is if you don't have pre-out and get such hard to power speakers or move into much large space, only way forward would to sell/give away old avr.

Emotiva is another name you can look at. Marantz too. Buy something simple - don't spend on features you are not convinced you use. Remember - most AV gear from Denon/Marantz/Emotiva/etc will have distorsiuni very small compared to the best speakers. The caveat is to not overdrive them into clipping.

Short and simple answer is no. Revivers provide the power / amplification. The receiver is the brain and an amplifier is the muscle.
