    Default HTPC built in Amplifier Passive speaker PCI card or drive tray

    Hello all.

    I have been researching HTPC for over a year now.

    I intend to build one when I can establish how to achieve a built in amplifier.

    The whole idea for me in HTPC is a 1 box solution for all media, so why is it I can not find a suitable amplifier with passive speaker solution that can be mounted directly in the HTPC case?

    Naturally there are heat issues that result from A, B and A/B class amplifiers but as a trade off D class have less heat build up for lower quality sound.

    I am aware that powering such a device (amp) will be an issue, so to avoid tapping into an exremely large PSU why not create an exteranl power supply into the case and by pass the PSU alltogether??

    There really are very few solutions to this.

    So far I have found these :

    Back in 2008 Msi released a AMD platform mobo with packaged PCI amplifier card.MSI Media Live Diva review - Motherboard reviews - TrustedReviews

    It appears this has been discontinued as no resllers have this in stock.

    Scythe has released a very small amplifier that can be installed in one of the drive bays.
    PC Hi-Fi: Scythe's Kama Bay Amp | silentpcreview.com
    But this really has little power.

    Another Concept would be to go all out and build a DD 5.1 amp with a modified version of this build:
    &#960-Amp - Introduction to the PC Integrated Amplifier System

    Possibly even modify a car audio amp and house this in the HTPC??.

    Here is an external amp that fulfills the user friendliness.
    Simplifi Digital, The world's first line of powerful audio amplifiers for the 21st century home

    I would love to take this amp and house it in my HTPC,.. Can it be done??

    What are the latest releases in regards to this issue??

    I am not alone here several other people want to establish the complete HTPC
    and although a complete system can be found such as this by asus
    ASUSTeK Computer Inc.

    I can't establish the intergrated amplifier component to this or the MOBO!!
    and..
    What I don't understand is in all my searches I am only really getting results from 2-3 years ago!! What has happened since and why is this not be being addressed?

    Many thanks..

    Hi D - What were you able to find out for the sound card with integrated amplifier question? I'm in the exact same boat as you, all my searches seem to find hits from a couple of years back. Surely there are better options out there? I desperately want to find an answer to the amplifier piece and then I can start building my dream PC!

    Thanks,

    Nisheeth

    Hi,.Nisheeth.

    I haven't been able to locate anything!! (hence my post)..

    From what I have learned there really are only 3 options.

    1. Find discontinued MSI motherboard from 2008.
    2. The Scyth drive bay mounted mini amp (only 10-15 watts!!)
    3. Build a complete amplifier yourself from various kitsets. (let me know if you think you'll go down this path)

    I have heard that MSI are still developing the Motherboard but haven't released any info.
    I also heard their motherboard with PCI amp had many problems and many simply did not work.

    I hope others will join this search for a Intergrated AMP for HTPC.

    Someone sent me a link to a company that builds small 10 Watt drive bay amplifiers -

    Kama Bay AMP 2000: Scythe - The Cooling Experts

    Interesting solution, fits in a 5.25" drive bay.

    I will be updating my site with the the bi-amp version of the pi-amp over the next month. It is more complex (and expensive) but the sound and power are worth it.

    You've been to it, listed in your first post. The bi-amped version uses an electronic cross over before the amps rather than passive cross overs in the speakers. I'm not an audiophile but I can tell you, the improvement is incredible. This build uses four Leach amps. It will be a couple of weeks before I get time to add the bi-amped version to pi-amp.com.

    What are you looking to build? I noticed that you are interested in "surround sound". A few years ago I realized that two large speakers driven by a good amp was the sound I was missing (lot more simple than messing with small 4+1 speaker cabinets). Just my preference though.

    havent tested it yet but ordered them a couple of min ago. for 5.1 sound you'd need 1x2014 and 1x4028 www.prel.de

    I am also looking for such, It is very hard to believ that this is not a popular idea.


    Several years back 1997 I built a setup with a car amp.

    I picked up the 12VDC off the PSU then drilled into the mobo @ the audio out jack and soldered in the new wires.

    It did work great then.

    I would like an HD amp inside my PC.

    Anyone pull this off lately thats could share your recipe/work?

    I am an electrical engineer and I have been planning on designing a PCI card amplifier for myself and hopefully to sell as well. I am wondering what features are most important to most people. I plan to build a simple and cheap two channel stereo version and a higher powered stereo version at least. I am also considering a surround sound version. I am open to input and encouragement if you feel so inclined. I hope to have something ready for sale in a couple months. Thanks!
