| Dynamic Headroom Class of operation has everything to do with headroom. A class A amplifier has by definition 0 db of headroom. I have always looked at the headroom spec as a way to make cheaper amps look better due to the term itself. IOW 'headroom' seems to impl... | |
| Tube Monoblock location? - Rack or near speakers? 5 meters is a long way to run single-ended cables. FWIW your dealer must not know what balanced lines can do. His statement is preposturous.But since the CAT has a single-ended input, and because the ARC does not support the balanced standard (whi... | |
| Favourite ECM Titles Steve Tibbetts! I play Steve's LPs at shows and people **always** ask 'what's playing?' Steve is his own combination of folk and progressive rock. Steve has been recording since the mid 1970s. One of the more serious masters of the guitar as well.... | |
| The Hub: What's that weird green light? Thanks Bill and keep up the good work! If things go right, I'll see you at Axpona (we really weren't planning on it until after THE Show, now I'm trying to shoehorn it into our schedule). | |
| "Tell the industry what you want" postingboard I'm with Spencer on this one- good quality tubes built the way the NOS tubes were would be really nice. | |
| Grounding phono cable The ground wire makes no difference, except that of course if it isn't there you will really notice it :) | |
| Stand out phono stages Lew, FWIW I don't think there exists any situation in which there should be no grid stop resistors. Without them the circuit is RF susceptible, and the preamp can also be prone to internal oscillation. | |
| Tubes vs. solid state. Guidocorona, feedback is very definately a factor in preamp design. A very famous Ampex recorder (model 351-2), used by RCA and Mercury as well as many others, featured a zero feedback record circuit. EQ of phono preamps is often handled in the fe... | |
| which is better ? MC phono stage or MM+step-up ? Yes- don't move the wire. It only breaks in with a signal though it. There are break-in boxes made for that that can speed things up.We have a number of customers using Acoustats. I've heard a few of them with our amps over the years. They are not... | |
| Tubes vs. solid state. Pinkus, the only issue with transistors is that without feedback, they will make more distortion than tubes will. However, if the design is competent, the higher orders will not manifest nearly so much as they will if feedback is applied. Its my o... | |
| Why Do We Use Preamps? A preamp serves five functions:control volumeselect inputsprovide any needed gainbuffer volume control from output cableand the least understood (but nevertheless very real):control the interconnect cable, i.e. prevent the cable from having an eff... | |
| Tubes vs. solid state. Minorl, of course there are electric cars too, and energy storage systems that are a lot better than the internal combustion guys would have you believe.There have been improvements in amps in the last 50 years. There are new topologies that did n... | |
| which is better ? MC phono stage or MM+step-up ? If you have a low output cartridge, the phono cable will need a good 200 hours. Its best if you don't disturb it! | |
| Can someone give me an explaination re: power amp. Kijanki, some tube amps will make higher distortion at very low power levels just like transistors. Others (SETs for example) the distortion becomes unmeasurable.Feedback is appearing more and more to be a poor means of ridding audio circuits of d... | |
| Tubes vs. solid state. Minorl, sounds to me as if you are saying something that I've been harping on a lot- that the playback system has to take into account the rules of human hearing/perception and obey those rules. Designing to specs on a piece of paper doesn't do it... |
