| Lightspeed Attenuator - Best Preamp Ever? 04-28-14: LuxsoundHas any one used his LSA with active monitors?mine do have an input impedance of 10KOhms, which is not the recommended 47Kohms.Output impedance of the source is extremly low though.any thoughts?It all comes down to what the sourc... | |
| Lightspeed Attenuator - Best Preamp Ever? 04-28-14: Digital3George will these cables fit the 2.1mm dc connector on the lsa.Yes, the Lightspeed Attenuator has a dc socket that has a 2.1mm centre pin, 5.5mm external, plug. The centre has to be positive which I believe the TeraDac is.Cheers ... | |
| Advantages of monoblocks No one has said anything about the disavantages of monoblocks. Here's a couple of main ones.1: You have a greater chance of (hum) earth loop problems with monoblocks, and the powercords will both have mains earth conections, and most like be pluge... | |
| Lightspeed Attenuator - Best Preamp Ever? I think he means one of these esoteric ones.http://www.ab-system.hk/index.php?route=product/product&path=78&product_id=172http://www.ab-system.hk/index.php?route=product/product&path=78&product_id=173Cheers George | |
| Tube Amp for Martin Logan Speakers 04-11-14: Atmasphere'Stable' means that the amp won't oscillate when presented with the load in question. Stable is a given with any amp, you may have missed the rest of the Martin Logan quote for the type of amp they recommend for their speakers.... | |
| Tube Amp for Martin Logan Speakers From the Marin Logan website:Quote:However, it is important that the amplifier be stable operating into varying impedance loads: an ideally stable amplifier will typically be able to deliver nearly twice its rated 8 Ohm wattage into 4 Ohms, and sh... | |
| Anyone have/ordered the Job 225? 04-09-14: Klh007The JOB 225 had sound stage and transparency/detail, at the expense of tone sounding leaner than the Veritas.This tonal balance has been stated by more than just by you Klh007, it was a trait that devilboy also heard when he used t... | |
| Tube Amp for Martin Logan Speakers I would like to thank Jan Didden for laying this furfie "NF feedback DOES NOT effect Z=out or damping factor" out in the open, in his usual calm and palpable way. His is a bottomless pit of correct information over at the much more techincal forum... | |
| Debating between Hybrid and Tube Integrated Amp Look for amps that have low output impedance, say below 1ohm. Some tube amps are higher than 1ohm output impedance you may find with these you end up with an amp that sounds bright without much bass or punch. As these speakers have some nasty area... | |
| Tube Amp for Martin Logan Speakers 04-04-14: Atmasphere : George, this may come as a surprise but increasing feedback does not affect output impedance. It stays the same, and the proof is simple.Oh yes it does Ralph it may supprise you even more, as I can show from many many others... | |
| Tube Amp for Martin Logan Speakers All depends on which way you look at it Al. Saying it's "optimised" for a 5ohm speaker does not mean it's a 5ohm tap.But giving figures as exact as in 1/10th's, 4.7 for damping and 1.5ohm for output to me is far more exacting.And from these two fi... | |
| Tube Amp for Martin Logan Speakers From here Al. At the The Manley website. http://www.manley.com/msn.php Features and Specifications Manley Snapper Damping Factor: 4.7Cheers George | |
| Tube Amp for Martin Logan Speakers OK Almarg, I'll split hairs with you. With a measured damping factor of 4.7 and an output impedance of 1.5ohms it's closer to an 8ohm tap than a 4ohm tap. But all this can change with a bit more global feed back to raise the damping factor and low... | |
| Tube Amp for Martin Logan Speakers Almarg/Unsound/Bifwyne: Looking at these figures again the Snapper's speaker termianls are a 7ohm tap to be pedantic about it.Cheers George | |
