| How much gain is needed in a Phono Preamp for a 0.2 to 0.3mv low output moving coil? Ditto - VPI Dynavector 20x2L with 15dB SUT and 46dB on phono pre (61db todal) works really well with still enough headroom. | |
| Can anyone listen to side 1 of Tchaikovsky "1812 Overture"? I'd check your cart setup if you haven't already. Also, I believe VPI recommends setting VTF on the higher end of the scale for carts. YMMV | |
| Can anyone listen to side 1 of Tchaikovsky "1812 Overture"? No problems with the Telarc 1812 on my VPI Scout II and Dynavector 20x2L, even at high volumes (using SW too).. | |

| Biamping with very different amps Not crazy. But you will typically need a means of adjusting gain as between the separate amps to make them equal. Usually done at the active crossover stage. | |
| B&W 801 vintage speakers in small space I would replace the caps in both the B&W and Threshold. Will sound like new again. | |
| JL Audio F110 Fathom pops... My f112 is still running strong since 2009 with no issues (knock on wood). | |
| JL Audio F110 Fathom pops... Definitely call JLA. Could be the beginnings of capacitor failure on the power supply board. | |
| Bi-amping To get the real benefit of bi-amping you need to add active crossovers and bypass the passive crossovers in your speakers. Then you'll need some measurement tools to dial in the crossover frequency, slope, etc. A lot of work but definitely worth... | |
| B+W 801D upgrade crossover Why do you want to upgrade the crossover? Is there something your are trying to fix? | |
| Bi Amping my B&W Matrix 800s There may be 4 PCBs but the 800 is essentially a 3 way with multiple driver arrays. The 802 is also a 3 way but with 2 LF drivers. | |
| Bi Amping my B&W Matrix 800s I purchased my 802s new in 1992. They were not overdriven. Caps, even polys, dont hold their specs for 20+ years. Best way to see is if you measure their ESR. Also, if the 800 is anything like the 802, they used cheap Bennic lytic caps. | |
| Bi Amping my B&W Matrix 800s The passives on the 802s were a bit easier to remove and replace. I did it myself. Used Mundof caps and Vishay resistors. Did not use polys for the electrolytics. | |
| Bi Amping my B&W Matrix 800s On my 802s, there are 2 PCBs for each speaker that make up the passive crossover, one for the LF and one for the MF and HF. I replaced the capacitors and resistors. But then I went with active crossovers for the SW, LF, and the MF/HF combo. | |
| Bi Amping my B&W Matrix 800s Mine looked great too. But they did not measure well on the LCR meter. I replaced them and I recovered some better low freq response I didnt know I had lost. These matrix series were built in the late 80s to early 90s so that is not unexpected. |
