| Amplifiers:A Keeper for Life. Do you know of one ? Dhcod, I've read many similar comments about the ARC D70 Mk2, including from a member who happens to be an authorized ARC repair tech. I wonder if ARC can recondition old D70 units and bring them up to original spec?? I ask because the D70 might m... | |
| room makes or breaks Agree with Ct0517. A'gon should add a "Room" category to its list of topics. My rig is located in a finished basement with weird dimensions and a low ceiling. It is carpeted and furnished, which may be a good thing. I'm sure much more can be done,... | |
| about the kt 120 tube Marc, ... short answer is no. Reason is ... I forgot. Haven't heard or read anything else about the KT-150 to date. I certainly would NOT drop this monster into my amp without an OK from ARC. As I am sure you know, ARC agonized about the KT-120 fo... | |
| What ohm to set amp Thanks so much Al. But as I said, I'll keep my day job. ;>') | |
| What ohm to set amp Al, thanks again for the education. So to restate what you said above, "[t]he tighter the regulation, meaning the smaller the +/- number, the LESS the voltage will increase as load impedance increases, and the LESS the voltage will decrease as loa... | |
| What ohm to set amp Thanks Al. Would you kindly clarify my understanding of the Voltage and Power Paradigm area just one more time. At least with my tube gear, ARC publishes so-called output regulation stats. In the case of both the Ref 150 and VS-115, output regulat... | |
| What ohm to set amp Al, I am somewhat familiar with the Ayre being touted as a zero feedback amp. So if it doubles power if the load drops in half, and halves power if load doubles, how does the amp manage to regulate the amount of current being shown to the speakers... | |
| What ohm to set amp That's kinda what I figured. In a sense, the 4 ohm switch is protective. So .... as you mentioned if the impedance switch is set to 8 ohms and the amp is pushing power into a 16 ohm load, the power output should be roughly one-half the amount whic... | |
| What ohm to set amp Thanks Al. Glarff means an inchoate stream of consciousness. Going back to the OP's Q re the MAC SS amp, I am just guessing here, but perhaps the 4/8 ohm switch avoids power doubling at 4 ohms if the 4 ohm switch is used. Perhaps the amp is more s... | |
| Soundstage vs background noise? Just an addendum to Ralph's post. Not only may the tubes be shot, but if the tube gear is old, it may be time for a recap too. I am a card carrying tube-head. So yeah, tube gear requires a little more care and feeding, but it's kinda fun, gets me ... | |
| What ohm to set amp Kalbi .. , don't know much about the Mac or SF impedance curves. So I only add this comment because it might help focus your discussion with MAC tomorrow. As I've come to better understand with my own gear, using the lower impedance taps on my tub... | |
| Preamp Headroom Question Ralph, sorry to sound dumb, but not sure what you mean when you say "how much noise there is when the needle is in a good silent groove." Does that imply when the record is spinning?? I ask because I checked the phono noise level with the linestag... | |
| Preamp Headroom Question Thanks Al. Easy enough to check. Next time I turn my rig on, I'll turn the linestage gain up to 80-85 clicks on phono setting, with the TT running -- but leaving the tone arm elevated off the record. That should be a good test to see how much nois... | |
| vpi JMW arm lengths Only way to know for sure is to call VPI. | |
| vpi JMW arm lengths Brf is technically correct. But he also confirms what I wrote. Even assuming you are willing to move the base, it would be helpful if VPI had a kit. For example, I switched out my Classic 1 tone base for the Classic 3 base. VPI sent me a kit with ... |
