Speaker configuration Marantz 2270
The 2270 output stage is optimized for 8-ohm speakers; power output into 4-ohms is lower. If you can avoid speakers with low impedance do it. I agree with Elevick - go with a sub if you can afford it. The problem is going to be finding satellites ... 
Velodyne DD Plus: New King of the Jungle?
I picked the DD18+, Sonicray, because my room is effectively 22x38x14 (I'm guessing), and my system is set up in one end of it. I wasn't sure what it would take to energize such a large space. As it turns out I probably could have used the DD15+ w... 
Velodyne DD Plus: New King of the Jungle?
Johnk, I wasn't implying that I thought you used 18" PA drivers in your super-woofer, I was saying that even rock bands that use subwoofers with 18" drivers in their PA systems usually have specs that are something like -3db @ 32Hz. So if classica... 
Velodyne DD Plus: New King of the Jungle?
So, Johnk, just curious, what in music generates such bass pressures? I was just at the symphony last night, and it is remarkable how little bass a symphony orchestra generates during a typical program. Even in rock and roll, a DD15+ can approxima... 
Velodyne DD Plus: New King of the Jungle?
I'm sitting here listening to a newly installed DD18+ with Revel Salon2 mains. I thought the Salon2s had pretty good bass... well, with the DD18+ it's a whole new universe, and this universe has has absolutely compelling, seamlessly blended bass. ... 
Best speakers to use with Mahi Mahi amps
Not to be rude, but you've got this backwards. Speakers vary far more in sound than amps do, so speakers are the most important component to choose first. Nonetheless, given the low power of the Mahi amps I'd choose some very efficient speakers.Ha... 
Revel Salon2 vs Wilson Sasha
Amazing how one could read this thread and note no correlation between the preferences expressed. Not that this thread is any different than so many others on this forum.When choosing very costly speakers, like in the $20K+ range, you eventually m... 
Why no reviews of the Magnepan 3.7 in Stereophile
Funny, that's one reason I like JA. All solid state, no vinyl, no delusions. Well, maybe just one. He still argues that cables make a big difference now and again. No one is perfect. :) 
Why no reviews of the Magnepan 3.7 in Stereophile
I think it's because many frequency response deviations are either pleasant (saddle-shaped curves) or inaudible with music. 
Why no reviews of the Magnepan 3.7 in Stereophile
Beave, Stereophile has a completely different business model than Consumer Reports. For one thing, CR is a broad-based testing organization with a huge subscription base, and operates as non-profit that takes donations, like NPR. Stereophile is a ...

"Sounds like the consensus is that the original CD redbook format engineers did a more than adequate job, at least in theory."Well, I would have said the red book CD is "just adequate". I think reducing the word length or the sampling rate might h... 
speakers for 24/96 audio
Well, Bryon, that was a very interesting article. I'm not sure what to think after reading it... is this yet another investigation into a micro-problem that doesn't really affect music reproduction, or is it a significant factor? I certainly don't...

"Irv, keep in mind that it is generally accepted that signal can be perceived at levels that are significantly below the level of random broadband noise that may accompany the signal. 15db or more below, iirc. So amplifier noise floor is not reall...

"Kijanki, are you implying that 24 bit data words have a "finer grain" than 16 bit data words? That each bit represents a smaller incremental signal level? ""That's the basic reason to us more bits in each sample in digital signal processing of an... 
How does Revel Ult. Salon II compare to B&W 800D?
There have been so many threads on this topic. In this price class you absolutely must listen for yourself, and whatever is said here is just for entertainment.I just had a chance to hear the latest 800D recently, and it was basically the same as ...
