Generally, if there are L + R stereo sub outputs, they are line outputs that could be used as preamp outputs (as opposed to mono sub outputs) if they are full-range without any low-pass filtering.

In the case of the IDA-8, these full-range outputs originally had 3X gain (6V) as opposed to more-or-less standard 2V, and therefore were described as subwoofer outputs and not preamp outputs.

However, as of August 14, 2015 all IDA-8 shipped had sub outputs with a default of  1X gain (2V), with 2X and 3X gain available on special order.

Thanks. I had forgotten I'd read about that. I've sent them an email as I don't know when mine was manufactured

It is of little consequence, since your sub has a gain control to get the right balance.

So the  different voltage output will only affect "fixed" volume subs.

Hello My name is Pappy and i am joining this group because i just ordered a Nuprime IDA-8.
 
Does anyone know if it still comes with two remotes?

Thanks

No, it was never meant to come with 2 remotes :)
LONG time ago, when we first introduce IDA-8, the original remote was not good enough.  So we made a new remote in later production. But since we have spare remotes, we just include them while supplies last.  The 1st remote stocks have long gone.

Are there particular models of speakers that you (or anyone) has found to make a noteworthy pairing with the IDA-8?

I’ve owned an IDA-8 since they first hit the market, and I still like and use mine. I’ve used it to power a pretty wide range of speakers in this time. Remember: It’s only 100w/ch, so it won’t do well trying to power low sensitivity speakers or speakers in a huge room.

Okay, I’ll provide two groups - one for speakers that didn’t seem to pair well, and one for speakers that seemed to pair well. [I’m using my phone to type, so I may make changes once I get home.]

Inferior pairing:

Fritz Loudspeakers LS/5-R (83.5dB), Daedalus Audio Apollos (96.5dB), PranaFidelity floor standing speakers 'Vayu', Lawrence Audio Cellos
I'm back on my laptop, so here's a little more info: The LS/5-R monitors are hungry little guys that really need more power to 'sing'. The IDA-8's 100w doesn't do them justice. My Apollos are very efficient, but they sound thin when powered by the IDA-8. I don't recall the Cellos' efficiency, but they, too, sounded thin. The Vayu sounded a bit thin, too.

My take away is that the above big speakers just sound better with more robust amps.

Good pairing:

ProAc Response D2, Adelphos two-way monitors using SB Acoustics Satori drivers designed by Jeff Bagby (87dB), Daedalus Audio Pans (94? dB), PranaFidelity Fifty/90monitors, Dynaco A-25 speakers, Paradigm Studio 20 v.3, Wild Burro 8” full range drivers on Betsy OB baffles, and CSS Audio Criton 1TD.....(pretty sure there were a couple more, but I don't recall right now).

It seems as though mid-efficient two-way monitors just seem to pair well with the IDA-8. It's got an almost tube-like sound with these speakers. I've got the IDA-8 powering my Adelphos monitors in our BIG family room. This room sucks bass out, but midrange and above frequencies sound great. I've got my TV and a Mac connected as well.
