Audio Physic Virgo III compared to the SF Cremona
has compared these 2 speakers head to headIncidentally, I have. They are quite different in their inherent reproduction details. As Larry suggests, you'd have to consider numerous parametres (other than listening extensively to both) in order to c... 
"Power hungry" speakers
JM Labs originated as a speaker manufacturer (JM= Jacques Mahul, the designer of said speakers). Allegedly, Focal acquired the speaker manufacturer who now operates as the finished (consumer) products division of Focal. So it wasn't quite a matter... 
Is it best to use a 5-channel amp for biamping??
Arthur- IMO using 4 of the Krell's channels should make a difference. I'm assuming the B&W's bass & mid-hi x-overs are discrete (not connected) of course. You should have better control and response in the low frequencies.Planckscale- sorr... 
Negative feedback, voltage and output impedance
How can there be a ss amp without ANY feedback?? I.e., Isn't some local feedback necessary?I'm not savvy on these subjects: which can explain my stupid question:) 
Harbeth question: Which speakers to keep?
Whatever you do, keep the ls3/5a. Best do as Jrd suggests. 
Current Trends in multi thousand dollar speakers
Ernie, I'm piping in here:what's wrong with a 24/dB drop below, let's say 30-40Hz (...) if a properly designed vented cabinet uses a nice low Fs, and the driver's happily within its excursion limitsIt doesn't sound impossible -- BUT:Problem seems,... 
Is it best to use a 5-channel amp for biamping??
Planckscale-Not quite; sorry should have been clearer. A little b/ground first:Two channel stereo: your amp receives a full-range signal (i.e. all the frequencies, typically from ~20Hz to ~22kHz) from the pre, amplifies it, and sends it as is to t... 
I made a pair of Voigt pipes and
Cdc sez:what makes a speaker sound boxyUsually a resonant peak @ 250-300Hz. The wood resonates giving a "honky" hue to the sound.Virgo- I respectfully disagree that putting the woof on the side is that bad an idea. What Joacheim is doing is keepin... 
Is it best to use a 5-channel amp for biamping??
No, no, Arthur-- you'll use FOUR of those channels to bi-amp: one channel for the right woof, another for the left woof, another for the right mid-hi's and another for the left mid-hi's. Total, four.The difference in sonics comes from driving the ... 
Current Trends in multi thousand dollar speakers
Isn't it utopia (no pun) to expect full-range response from a commercial passive, dynamic speaker??Ultimately, CAN there be such a thing as a passive, dynamic, FULL-range speaker within physical & electrical & COMMERCIAL reason??? Let's lo... 
Question re speaker or amp problem???
Probably the volume pot (contacts needs cleaning) or a lose contact somewhere along the line b/ween amp & speakers.Nothing a good contact spray or (if necessary) some soldering can't fix. 
Is it best to use a 5-channel amp for biamping??
If you're asking whether bi-amping (active x-over, or passive line-level xover) a pair of speakers is better than driving them in passive form -- you bet.If I understand the question: you're considering a 5channel amp in order to use 4 of these ch... 
Current Trends in multi thousand dollar speakers
Re: transmission line speakers, mechanical & electrical modelling is now available for quarter-wavelength speaker design. Never tried it -- but thanks to a few audiophile engineers it looks like we've taken a large step forward from the trial ... 
Understanding impedence matching
Chuck -- investing a little time in understanding Ohm's law will take you a long way towards understanding these issues. It's a bit like learning a language: in the beginning it feels daunting and impossible and then, suddenly, you loosen up &... 
Why is the trend to make separate phono stage
Dcaudio-I am looking at replacing my current pre-amp (phono & line)for the next ten yearsI've been in the same boat. Maybe a solution is, phono + volume control for the rest??? I.e. are you sure the active line's extra db are absolutely necess...
