T-Amp or Stereo Receiver for PC Setup?

post #1 of 7
Thread Starter 

Hi, everybody! I will be upgrading with the primary focus on listening to music on my PC, which is in my living room. I am wondering about the power source options. I have about $400 bucks total to get some cheap floor stands, cables, the bookshelf speakers, and the power source. Therefore, I am only trying to spend around $100 bucks on the receiver, give or take some. (I am concerned about heat issues/damage with monitors with an internal amp, so I am trying to stay away from them.)

 

What do think is better for me, a micro T-Amp or Cheap Stereo Reciever and why?

As I see it there are T-amps like the Lepai LP-2020A+ ($28), which is suspiciously cheap and doesn’t have much power. There also is the Topping TP20-MK2 for under $100, it has good reviews, but only puts out 13 WPC. Then there are also some low end receivers such as the Sony STRDH130 for around $100 bucks. Used or refurbished receivers are also an option. I would think that receivers, since it has more hardware, would be of lower quality and have less power. However, the output wattage seems a lot stronger on the receivers and is pretty low on the T-Amps. I am sort of concerned with damaging my speakers with those low wattage T-amps if they don't have enough power.

 

One other thing, related to installation on the PC. I would like possibility to be able to upgrade my system with active subwoofer, if needed later on. My PC has 6 audio ports (Line in, Line Out, Side Speaker, Rear Speaker, Center/Woofer Speaker, Mic In).

To add a active sub, would all I need to do is connect the speakers to the line out and the subwoofer to the sub port?  

Should the possibility of having a powered sub affect the decision on the receiver or amp? (Should I try to find an amp/receiver that has a sub port on it?)

 

Thank you

With that budget, I'd probably go for active monitors.

FYI, you can't damage a speaker by giving it less than rated power. This is a huge myth is the car audio world as well.

Not even if you drive it to the limits and beyond with heaps of clipping?

If you can stretch your amplifier budget a bit the Mini-1 is a fantastic little Tripath amp.

How will you manage to push the driver to its thermal and mechanical limits in that situation?

If you could damage speakers by under powering them, you would blow them every time you lowered the volume on your source.

You can blow the tweeter by clipping the amp. IANAE, but my understanding is that the when clipped hard, extra power will go to the tweeter, much more than normal, and overheat it.
