rich0372 Posted September 15, 2005 Share Posted September 15, 2005 How many of you are using amps by different companies would this make a difference I have a 3 channel amp for the front 3 speakers does it matter if I get an amp front another company for the remaining 3 channels Rich Quote Link to comment Share on other sites More sharing options...
MrMcGoo Posted September 15, 2005 Share Posted September 15, 2005 Rich, Most solid state amps sound the same when not clipping. The thing to look at is the gain ratio. For example, when one volt of input goes in, that there are 29 volts of output. When that ratio is close for both amps, your channel level adjustments will stay level at any resonable volume. Other things to look at are the signal to noise ratio, noise in the first watt, and the ability to drive 4 ohm (Heritage) and 2 ohm (Reference) loads.

Shade Posted September 15, 2005 Share Posted September 15, 2005 It would probably be fine, as long as you don't use an amp with a far different sound. Ex : mating one 3-ch amp that has a cold/bright sound with another on the warmer side. It would be preferrable to get the same model you currently have. If cost is an issue, you might keep an eye on the used market. Quote Link to comment Share on other sites More sharing options...
Lurch Posted September 15, 2005 Share Posted September 15, 2005 I agree with the comments on gain structure. I use 2 channels from a B&K Reference 4430 for the mains and 5 channels from an Anthem MCA-5 for 7 channels total. The B&K has an input sensitivity of 1.4 volts and gain of 28 db. The MCA-5 is 1.35 volts and 29 db. Matching is not a problem. 1 Quote Link to comment Share on other sites More sharing options...
