orian makes decent stuff. the xtr series is alright I beleive for the money there are better amps on the market. my opinion. but if you really like orion then I would have to agree the hcca are really good but they cost a bit much. It also depends what your after. raw power or clean consistant power. If you are not looking for earth shattering bass I would recommend the Xtant amps preferably the X series. that is if money is not an issue. or the A series. But if you are a bass head which you may be if you are looking at orion stick with the HCCA stuff. they are very powerful.
