    I trying to decide if I should use a TX-NR515 or UPA-700?
    The speakers I am using are : Pioneer SP-BS22-LR, a Pioneer SP-C22 and a Pioneer SW-8MK2.

    At first glance, the A/V receiver right? Well, I have it and am about to return it and get the UPA-700. Tell me I am wrong or right!

    Here is the history: Had a $70 5.1 computer speaker setup. The speakers died, and it is time to upgrade to some better speakers. I like the speakers, but they are still returnable too, incase 6 ohm speakers are crud for some reason I dont know yet! so, speakers aside, how do I power them?

    Here is my setup: I have a computer with HDMI out*. I have a projector I use as a TV hooked up to my computer. I have the Pioneers hooked up to the TX-NR515. My computer has spdif out, 5.1 sound over 1/8th jacks in addition. This is my computer.

    As far as I can tell, I am using my TX-NR515 as nothing more than a UPA-700. Why not use a much, much better amp if all I am using the TX-NR515 is as an amp?

    Plus to using TX-NR515
    1) HDMI to transmit audio over

    And the UPA-700 would lose those plus's
    1) using 1/8th jacks to transmit over instead of HDMI

    Am I right on my assumptions? Am I crazy to switch from TX-NR515 to a UPA-700?



    *HDMI and S/PDIF, I have both connected. I started a few songs, and during the songs switched from optical to HDMI. Over my TX-NR515 they both sounded nearly the same. Optical was slightly quieter, that is about it. I know on paper they are the same, but I got to test it. Sounded the same.

    If you only have 1 source, and you'll be happy using your 6 channel analog, sure.

    Your computer can control the volume.

    And optical=digital coax=HDMI for all audio that isn't lossless anyway. As long as your computer can change lossless to PCM, instead of bitstream, your are good for lossless audio.

    Thanks. Now I have the peace of mind to start with just the amp, and add the UMC-200 or other AV Preamp down the road.

    How do the Pioneer SP-BS22-LR, a Pioneer SP-C22 and a Pioneer SW-8MK2 compare to the others recommended here? I am a newbie, so only know 8 ohms is better than 6 ohms. The pioneers are 6 ohms.... budget is $300ish (spent just less than $300 on all 4 speakers)
    › Nominal Impedance.......................................................6 Ohms
    › Sensitivity (2.83 V)...............................................................85 dB
    › Maximum Input Power.........................................................80 W
    › Cross-Over Frequency.........................................................3 kHz
    Spec Sheet (PDF)

    The Bic America Adatto Dv52Si Adatto Indoor/Outdoor Speakers (Black) were recommended, they are 8 ohms. They are way less, $70 and paired with BIC AMERICA DV-52CLRB 5 1/4" 2-Way Center Channel Speaker (BIC AMERICA DV52CLRB) is $130 (no sub).

    or

    klipsch HD theater 300 is $400. Should I have gone with that instead? It is also NOMINAL IMPEDANCE: 8 ohms compatible.

    Did I get the wrong speakers?

    8 is not better than 6. Just like 4 is no better.The speakers fine.

    I found this after you answered, I wish I had found it sooner. This seems to plainly explain what ohlms is to us beginners.

    I need to read it about 3 more times to really understand it, but I wanted to post it because it might help someone else.
