| Bel canto problems Heat is an issue and I am experimenting w amps outside the cabinet. Interestingly, the 150s and one of the ref 600 m amps have been fine in the cabinet the entire time. The 150's and one of the 600's that don't turn off could have a slightly h... | |

| What does an impedance-matching issue "sound" like? So I don’t think tubes are the issue, but it’s the 3 ohms That 3ohms at 110hz with -50’ phase angle at 75hz to me is an issue, especially with SE tubes, this is where all the amps power is needed for bass repoduction. I find it hard to believe a ... | |
| What does an impedance-matching issue "sound" like? @almargOoops sorry, just saw what he said in the first sentence. added a 2nd Luxman MQ-88uSE to my 2 channel system, bridged to mono so I am running a Luxman to each of my 6ohm Volti Rivals In any case that phase/impedance load around 100hz is not... | |
| What does an impedance-matching issue "sound" like? jsqt OP Bridging amps in solid state,Doubles the output impedanceHalves the damping factorIncreases the distortionHas have the current ability. Makes the amp less stable into lower impedance’s to what it was in stereo. So everything takes a hit, e... | |
| KEF-LS50 with REL T-Zero? Anyone? randyhat I wouldn’t use a sub larger than 2 x 8" max or at a pinch a very fast servo controlled 10" sub. As your crossing over from a 5.25" driver. 12" or 15" subs will be too slow to mate properly. I would also try blocking the port on the LS50 ... | |
| Lightspeed Attenuator - Best Preamp Ever? Thanks Mod's, one sic unit. | |
| Can I use a split? While the DAC has a tube-based output stage and therefore might have a relatively high output impedance For sure, it only has 1 dual triode, half for each channel. If it had two then it’s possible it could have had a white cathode follower outpu... | |
| Integrated amp for Thiel 3.7's Btw, anybody have thoughts on the Nelson integrated (250) Generally push/pull complimentary Mosfets aren’t too good at doubling wattage and supplying current down into that broad band of 2ohms, I stick with and look for BJT (bi-polar) amps. Maybe... | |
| KEF Reference 207/2s or Blade 2 Given the speakers are easy to drive, might the Ayre VX-5 Twenty be adequate. I’d stay with the JC1’s, and use them in hi bias mode, and try to vent the heat away somehow. John Curl is no slouch, I’d put higher up the design ladder than Charles Ha... | |
| why so many gryphon diablo 300 integrated for sale now? why so many gryphon diablo 300 integrated for sale now? If they were there, there not now, they were all snapped up I know a few people that went from Gryphon 300 to either the Luxman 509 or 590 Models because they are warmer sounding. Some f... | |
| Soulution or CH Precision Unfortunately there are no impedance v phase graphs done on either of those two speakers. So it's hard to comment what sort of amp would suit the best. All you can do is read all the reviews of the speakers with what amps were used, and make a edu... | |
| Can I use a split? Tell us the model of the dac and it's "output impedance"And the "input impedance" of the amp (model), and headphone amp (model).And we’ll work it output.Cheers George | |
| KEF Reference 207/2s or Blade 2 Both are quite easy to drive, and your JC1's in high bias mode should be a very nice amp for them both, if a little bit over the top.Just go with the ones that sound the best if you have a chance to listen to them both with your JC1'shttps://www.s... | |
| Transformer coupled vs Capacitor coupled? wig Transformer coupled vs Capacitor coupled? So long as the stage before is good in design low output impedance and has more than enough current and all your doing is stopping any dc offset, then a good cap is far better than a good transforme... |
