This is what i suspected as I have read here on the forum that there is not a big difference (the law of diminishing returns) SQ wise between the 7702MKII and 8802A. It seems from what I have read that the difference with the Dirac would be larger than the difference between these two processors.

If both processors were running Dirac Live room correction using the same power amps and speakers, you would be hard pressed to hear a sonic difference, IMO.

I will get to the other thread but I don't have time for the next couple of weeks to read through a gazillion posts so my question is can I set 15Hz HPF filters for all channels and boost the bass in all channels to my hearts content while still enjoying the benefits of Dirac?

Can the 88a function as a preamp if your only source was a PC, or something like an Oppo BDP-105? Assuming that you have outboard amplification/dsp.?

The recent upgrade to the 88A bass management allows it to function as a preamp, although it will be missing many of the features of a true preamp.

Setting the HPF is not an issue. Boost is limited to 9dB, so if that fits within your definition of boosting to your hearts content, then yes.

Couldn't you shoot even lower on the prepro line?

Just get the lowest you can. Any cheap avr with the number of channels you need

A receiver based pre-amp/processor is a total waste of not only wall power but the internal amps as well as i already have amplifiers and I wouldn't want to drop any lower in the line than that. Still not sure what I am going to do yet.

So you'd rather pay more to have the amps removed and otherwise get the same thing?

I would rather save wall power which I pay for and have XLR connections since I own and use all MIT XLR cables.

Do you have any data to support your contention that high-voltage XLR outputs require less power than idling amps and lower-voltage RCA outputs?

By the way, if anyone is considering the 2x4 advanced plugin, it should be noted that the already-low maximum delay of 7.5 msec in the 4-way advanced plugin has been reduced slightly to 7.2 msec in the 2x4 advanced plugin. See video below. The documentation of this plugin says 7.5 msec, so that is apparently wrong.

Edit: If the video appears to hang, just manually drag the slider to 22:35 elapsed time.

Curious why they would do that, as is I need more than the 7.5 in the advanced 21 as it is. What would be the reasoning forn keeping it that low?

Maybe they are short of memory or processing power. The 2x4 advanced has an input matrix that the other plugins for the 2x4 don't have. An additional restriction with the 2x4 advanced is that there is a maximum of 5 biquads per channel rather than the 6 of the 4-way.

Bottom line is I plugged in a meter to measure the wattage draw from each as I have an A/V receiver that I use whenever I am waiting for whatever newer pre-amp/pro i am waiting for arrives and the A/V receiver with the built in amps draws FAR more wattage! It was noticed in my electric bill as it had shot up noticeably during that month that the receiver was in use so that's why i took the meter to it as that's the only change and my suspicion was correct, soon as my pre-amp pro arrived my bill went back down to normal, is that convincing enough for you (as if it matters)? Anyways that's enough of that. As far as cables go in any forum it's a stupid and wasted dialogue to get into(for me and quite a few others), I can get things at dealer cost so it saves me a lot of money so even if I didn't think it made a difference sonically then I could sell it for a profit anyways so, for me, i am a winner either way. It's interesting though because when I do read people getting into these conversations about wire and cable I send them a PM and, for them they believe that they do hear better sound quality with certain higher end cables over others and for whoever thinks they do whether there actually is or not is nobody else s business and they do not have to justify it to anyone, period.

SO what you are saying we both have the same car "BUT" yours is red and mines white BUT yours is better right ?

No difference between Balanced & SE! Unless your going like 100 plus feet.

Dude-wasted and pointless conversation just like the last guy, get back on point to the thread which is miniDSP not cables or balanced vs unbalanced.

Dude, every post in this thread you have posted has been a waste. Talk about calling the kettle black hey !

I put a meter on my amp because I want to consume power /fail !

That was answering the last persons question that HE brought up not me. Get OFF IT and back on topic, Don't try and add fuel to keep something going that doesn't belong here, be a man and take the high road. Look at yourself in the mirror objectively if you can and be honest with yourself and admit that this post you created is the waste.Again, get back on topic.

Even taking your assertion at face value, the above text is an example of the slipshod reasoning one generally expects from wire-worshipper types.

You compared an unnamed older AVR to"whatever newer pre-amp/pro." Anyone thoughtful will instantly recognize that as a useless and meaningless comparison. What would actually be interesting is numbers to show comparative in-use energy efficiency of ampless AVR and amp'ed AVR from the same generation, used as a pre-pro. For example Anthem MRX720/1120 vs. AVM60, Yamaha 5100 vs. 3050, Denon 7200 vs. Marantz 8802, etc.

I don't know the answer there (are they materially different in terms of energy efficiency or not?) but my hunch is that the differences are very minor at best.
