Hi Joel, I am not familiar with the 374A but I have a couple of 1250s and a 2500. The 1250 puts out 1500 watts on most bands, needs very low drive and has the WARC bands and Pat has good support but you will probably never need it. Tune the amp carefully and load it heavy and it will play just fine. BTW a 2500E would be better match for a 1000D hi hi. 73 Steve VE3TU
