[QUOTE="Doxquzme, post: 8869518, member: 689267"] First - "They said if my amp had an "high level input" then they could get some decent quality out of it without installing DSP." That is just bonkers, one uses high level inputs only when they don;t have another option, not sure where they were going with that , makes absolutely no sense. I hear ya on that (the one you have, wasn't sure which) HU, it'd be a chore and expensive for sure. As for the two Helix units, I don't recall the difference between the two Helix units, most likely marginal and a newer version of the same. I have read on the various sites on the RD1 and its mostly favorable but not when compared to the Helix. Helix is the current intent boner and has been for a while and is considered one of if not best in it's class. Don't let anyone selling RF to talk you out of it, Helix is a rock sold product. I would have gone for the helix myself, the $1200 pricetag killed that when I was able to pick up the AudioContorl DM810, remote and BT adapter for $600, a display unit from a local shop that was going out of business. Nobody here is going to take the RD1 over the helix to save a $100. I could not get the particulars on the chips used in the RF or the processing power, etc. The support for the Helix is outstanding as is AudioControl. Brand new firmware with the AC is atop down new release and it's very good. You'll find very little to no truly negative Helix reviews in these forums compared to others. As for the Sub, it's a great product. Make sure to get 1 lb of Acosta-stuf (1 lb per cubic ft of airspace) and stuff the chamber as it improves the overall performance, makes a difference. As for the components, get the hybrids if you can, they use the Acuflex coated tweeters and they are steller! The cheap morels for the back should be fine. Even the Hertz in the same price range are not as good. There is a reason why the Piccolos go for a grand, ACUFLEX! Lol, jk, but you get my drift.
