| Advice on replacing 12 in woofer in Martin Logan Monolith III's They were too expensive to make that’s why they were stopped, but many were sold, dig deep for used ones.The SV-12 were only one I found that went low enough and up 130hz, also known as the Meniscus SW1284. There were some that had as good LF perf... | |
| SuperTweeters -- Yes Please! But is that the delicate smell of ozone I detect Yeah, it's not bad, just leave a window or a door open and your fine, good mozzie deterrent.Cheers George | |
| SuperTweeters -- Yes Please! Put a pair of these atop your speakers, they come in around 4.5kHz and you have highs/upper mids you never thought possible, delicate highs that just dance across the sound stage in front of you, you swear you can reach out and touch them. The air... | |
| Advice on replacing 12 in woofer in Martin Logan Monolith III's Yes, the driver ML commissioned Eminence to make is rubbish compared to the rest of the speaker, it has a one note bass, I’ve got all the T/S parameters on it, not good.The ACI-SV12 ( Meniscus SW1284 ) I matched and replaced them with are miles be... | |
| DAC for CD transport Cambridge Audio CXC can play also hybrid CDs This is a first for me.Are you saying this transport only reads SACD and output’s it on the spidf digtal output.PS: Just did some diging, it only reads the pcm (redbook) layer not the sacd layer. Can’t... | |
| I'm considering replacing my passive preamp with a tubes. Is it worth it? without the clicking volume control. It’s not a "clicking" feel, it’s a smooth rotation, but it does activate different relays inside to give 128 levels via a micro processor. Relays are far better than any normal volume control, as they have far... | |
| I'm considering replacing my passive preamp with a tubes. Is it worth it? t is most important that the output impedance of the preamp be a good match for the amp. Tested Stereophile: "Bryston measured just over 33k ohms at the balanced inputs, just over 47k ohms at the unbalanced." This is a match for any preamp, passi... | |
| Transformers humimg........again atmasphereWhat is your line voltage? It should not exceed 125V for more than a second. If its high that could explain the problem. +1 for checking this.Canada is supposed to be 120v. In Australia we’re supposed to be 230v mine measured quite cons... | |
| I'm considering replacing my passive preamp with a tubes. Is it worth it? amritash I’m considering replacing my passive preamp with a tubes. Is it worth it? Schiit Freya at $699 with trial period, it has 3 different modes, low gain tube, low gain discrete solid state, and unity gain passive, balanced or single ended ... | |
| 3M's new Embedded Capacitance Material usefulness for "high End"? Ultra thin sandwiched mylar by the sounds of it, "loaded with sub-micron non-fired barium titanate ceramic particles" Some new sort of planer speaker 0.984252 of a thou thick, with no caps for the xover, utilising it’s own capacitance maybe???http... | |
| Impedance matching between 2k ohm phono pre and 100k ohm amps via passive pre Ah ok - that makes sense. Noob that I am, it did not occur to me that passive pre’s have in and out impedance. Yes the input impedance (if wired in normal fashion) is the the value of the pot, in your case 10kohm. The output impedance (at worst) ... | |
| Impedance matching between 2k ohm phono pre and 100k ohm amps via passive pre subterranean6 OP9 posts02-17-2017 11:50amI mean, I’m running this through this Sys passive pre, and the there is plenty of volume. I’m just wondering if I’m going to damage something... No, if you can do this then you have plenty of output from t... | |
| Impedance matching between 2k ohm phono pre and 100k ohm amps via passive pre "drive loads down to 600 ohms" !!!!! yikes. This is c**p if it's 2kohm output impedance, (say I said before about being a voltage divider) you'll end up with very little output.Are you sure the phono is 2kohms output impedance, or does it say ... | |
| Impedance matching between 2k ohm phono pre and 100k ohm amps via passive pre George - If I’m putting 2k ohm into a passive pre with an input impedance rated at 10k ohm, it means I’m not going to get 100% of the bandwidth? Signal? Yes you will. Just that you may loose a "little" total level (no dynamic loss) from the outpu... | |
| Impedance matching between 2k ohm phono pre and 100k ohm amps via passive pre The output impedance of the source is 2kohm, so the load it should be at least a 20kohm passive. The the output of the passive will be fine with the 100kohm input of the poweramp. Cheers George |
