| "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... | |
| symphonic Line RG4 III vs RG4 IV? Overall, the mod sounds reasonable & careful.As to changing the electrolytics -- of course: electrolytics *do* have a shelf life after all, and heat, etc, don't help them much... I've read good things about the Panasonics.OTOH, b-gates in the ... |
