    OHMs

    I am in the market for an amplifier.  From what I understand, one should have amplification that is rated for the impedance matching the speakers.  But most amplification is for either 4 or 8 ohms and the 5t and 6t have an impedance rating of 6 ohms.  What amplification would you recommend.  I have a receiver, but want a solid state amplifier like the Bosangwha Rev.2.3 Monoblock Amplifier.  

    Thanks!

    Re: OHMs

    I know nothing of the amp you happened to mention, but from experience, there are a few of us here that are operating on Emotiva amps and love them with our Aperion speakers.

     

    Judging from a quick Google search, it seems you're in the market for something considerably more high-end.  There will be some amazing amps in your price range that will suit your speakers greatly.  

     

    I don't know all of the science, but from what I've been reading, amps will have a 4ohm and an 8ohm rating as a matter of reference, but really, they operate all over the spectrum.  As I said, a few of us are using amps that having "ratings" at 4 or 8 ohms but operate our Aperions just fine.  Great, in fact.

     

    There are some serious discussions on AVSForums.com about high-end amps.  You might check that out also.

     

    Welcome to the forums.

    Re: OHMs

    Unfortunately I am only indirectly familiar with the amplifier you mentioned, however I can tell you in terms of quality and impedance it should be a good match with either the 5T or 6T. Without getting too involved here comcerning impedance matching, the most important thing to know is that any nominally rated 6 ohm speaker with a benign impedance curve will work perfectly with a nominally rated 8 ohm amplifier; nearly every 8 ohm amp/receiver I know of is perfectly stable into speaker loads that deviate no more than 25% of the amp's specified impedance. Usually one gets into trouble when trying to match a 4 ohm speaker and an 8 ohm amplifier (since a 4 ohm speaker will in effect deviate at least 50% from the amps specified impedance and therefore requires a 4 ohm rated amplifier).

    However the greater issue may be with how much power the Bosangwha amps can supply to our speakers. If you have 6Ts in a normal size room and don't listen at too loud of levels, the 18 WPC on tap with the chip amps you mentioned should be all the power you'll ever need since the 6Ts are a fairly high sensitivity design. However, if you're thinking 5Ts in a large room at loud levels, you may need something with a bit more juice, maybe at least 30 wpc of high current solid state power.

    Re: OHMs

    Also, I forgot to mention that if a speaker is rated at or above the amplifier's specified impedance, they will work together with no problems at all, i.e. a 4 ohm amplifier can handle any speaker rated at 4 ohms, 5 ohms, 8 ohms, 16, etc.
