I am unfamiliar with this company "Technical HiFi" also know as "Technical Pro" I was wondering if anyone has had an experience with their amplifiers! I am interested in their Technical Pro X-B5 amplifier and need some help as to whether or not this is a product worth buying or not. This will be powering my SDA SRS'S I have tried to find product reviews but have not been successful. Thoughts and comments are appreciated

Here is the link to their website.

    Thats a pro amp.You really want it for your home?
    The thing that scares me is how they describe the highs..."piercing"?? Not exactly what I would look for for home use.

    I am just looking for some raw power to get these speakers alive. I don't listen to the speakers loudly, but rather at low volumes for enjoyment of the sound they produce. Are they saying "piercing" in the sense of clarity of the highs (not sure)?

    Pro / home audio amplifiers i really don't have a preference on (is there a big difference? I dont know) they seem unique for home audio. The amplifier meets a price point in which i am willing to pay (not at retail as the website shows). For my application would this amplifier be something to consider buying as i am unfamiliar with this company and the specs.

    I would avoid pro audio amps in the home.

    I agree. I play in a band, and I can tell you that live music (bands and DJ) applications have very different requirements for amplification then home audio. This product competes with Crown, QSC, and others in that market. It's not ideal for home use.

    Sure, you could use it, but you would be better served (i.e., you'll have better sound) with products designed for home audio systems.

    I assume of course that you have typical home stereo speakers, and not PA cabinets designed for a band or professional DJ.

    Sky how is the amplification requirements different? Is the quality of sound going to be much different than using a home audio amplifier?

    I am not sure these speakers are typical for home audio :D, maybe for alot guys on this forum they are.

    Looking for what?Cheap...piercing highs.....gobs of power? I think this dude wants nightclub tunes at nightclub sound levels with nightclub sound quality.If so,a few benjamins is probably worth it to him.

    If you want alot of quality power, pro amps aren't really what your looking for. It's going to cost, too.

    Seriously though why are pro audio amplifiers not good for home audio usage?? I was just curious with the whole idea of using a pro audio amplifier (is power not power)? I have never owned an amplifier before and dont want to have a night club in my house. I just want to make the speakers come alive nothing more with an amplifier of some sort.

    No,power is not power,different amps are designed,built for different applications.Find a good amp for consumer use.What speakers are you driving? Sure you can add an amp to whatever avr your useing ?

    Then you definately need an amp.Block party ??? Re think that one.Block parties need PA speakers like DJ's use,these will loose alot of sound quality if you move them outdoors.
    But the reason you want them to come alive is because they are under powered,badly.Find a good used amp from B&K carver/sunfire,Adcom,Parrasound,Emotive and so on.Hopefully,you won't have to replace anything in the speakers from under powering them.Who knows,they are older and can probably use somethings replaced.Many threads here on doing this yourself.Great speakers pal,but you have to take care of these babies.

    I was just kidding about the block party/night club. I know, i really want an amp thats why i asked about this application type. I am sure someone could have a block party with these speakers, but i do not want to disrespect these speakers and wont be doing that.
    Thanks for the help and responses,

    Look for a big Adcom, or Parasound. Very simple clean designs. These are not the only two manufacturers, but a good start to find something good. Resale is very good on both of those amps.
    Ben
    Please. Please contact me a ben62670 @ yahoo.com. Make sure to include who you are, and you are from Polk so I don't delete your email. Also I am now physically unable to work on any projects. If you need help let these guys know. There are many people who will help if you let them know where you are.
    Thanks

    They aren't designed for what you want. Are they powerful? Sure, but the SQ isn't very refined. They are made for gobs of power, that's it. Dance floor kinda ****.

    Look for a Carver "T" or "TFM" if your on a budget. Or a used Sunfire Signature if you have the means.

    Here's a Carver TFM 55

    Here's a Sunfire Signature, It's on the high side and you can find 'em cheaper

    I mention them because I'm partial to Bob Carver's designs. Lot's of power relatively cheap.

    There are alot of different amps out there. What do you really want out of your system?

    To put it simply, to make sound you need to move air.

    The amount of air you need to move in a club or theatre is far greater, like 10 to the third power greater than the amount of air you need to move in your living room.

    So the amps and speakers designed for this situation are designed more for volume of air moved and not accuracy.

    Just like a studio monitor is designed to be listned to at a close range so they are designed for more detail and less loudness.

    Different tools for different purposes, if they all did the same thing they would be the same :)

    In more complicated terms, a true class a would amplify the exact sine wave, but a true class a makes a lot of heat because of the way the circuits work, it has to do with the overlap of the top and bottom portion of the sine wave, I am not an electricle engineer so I can't really properly explain it :) But as you move away from a true class a there is a distinct flat spot in the sine wave at the transition and it can almost look digital with a rounded top. But these generate less heat and are less prone to blowing up which is more important when talking about a pro amp.

    I am sure someone could explain it better than me but I did my best :)

    DeepBass, I think Mule has it about right. It might be oversimplified to say this, but it's basically correct: the pro amps and speakers are going for quantity over quality. Lots of volume that has to disperse over a wide area. Subtly is the not the primary concern.
