| 90db 4 ohm with tubes? Charles...., you are spot on correct. But to satisfy your own curiosity, check the published bench test reports on a number of the "Big Boy" speakers like Revel Salon 2 and Magico. They have some pretty rough impedance curves and the manufacturers... | |
| Audio Research Reference 5SE reliability Vladimir, if you are referring to a self powered sub, and you are sure that it has a 1K ohm input impedance, which strikes me as low, you are overloading the Ref SE by a very wide margin. Confirm your stats and call Kal at ARC. If he confirms my s... | |
| 90db 4 ohm with tubes? Dr. Mechans, I have beaten this subject to death with Al and Ralph (Atmasphere). Check my threads. Al is 120% correct. The ability of a tube amp to drive a speaker with wide impedance fluctuations with tight output regulation is a function of the ... | |
| Audio Research Reference 5SE reliability Anwar, check the input impedance of your sub. I suspect that the combined impedance load on your Ref 5 SE is less than 20K ohms. If so, you are overloading the Ref 5 and potentially degrading its already excelleant performance. Try Kal again. If y... | |
| Lyra Delos Stylus Replacement Options Dhcod, can Lyra retip the cartridge with a new stylus if the cantilever and suspension are otherwise intact? Any idea about cost and down time in the shop?Wntrmute2, get with the lingo Dude. LOL ;>') | |
| VPI Classic 4, any one have it? Hey Dave, I just "hot-rodded" my Classic to a "2.5," compliments of Mike at VPI. Check my system description. The upgraded version sounds a little better than my old Classic 1 tonearm base, but measurable in tweaks. It does provide a nice convenie... | |
| Lyra Delos Stylus Replacement Options Chip, I think the Delos is a better sounding carty than the Zephyr from the perspective of bass slam, bass definition, transparency, imaging and ability to extract details out of the grooves. But having said that, the Zephyr is a very, very fine c... | |
| VTA for Lyra Delos Just bought a pre-owned Delos (ed 1). Is the current Delos a new model or still ed 1? If so, what are the main changes? I picked my pre-owned Delos up for a very fair price and am very pleased. I'm keeping my Soundsmith Zephyr as back up carty. Fo... | |
| Anyone try this way to wire your loudspeakers? Al, I'm almost afraid to ask this Q, but here goes. Would it be a good, bad or neutral thing to use the 8 ohm tap for one speaker lead and the 4 ohm tap for the other lead? Regards,Bruce | |
| Audio Research Vs115 VS-115 maintenance tip. Just replaced the four 6H30 cathode follower tubes. May have run them out to almost 4000 hours. BIG, BIG difference. The amp definitely sounds better: tighter bass, more transparent, and so forth. I think in the future I wi... | |
| Audio Research Reference 5SE reliability Djcxxx, your MC601's input impedance of 20K ohms is the maximum load recommended by ARC. If you are running anything else off the other Ref 5 outputs (e.g., a sub woofer), the combined impedance load that the Ref 5 sees will likely drop below 20K ... | |
| When an amp puts out 90 watts.... Got it Ralph. But outside of the few exceptions like your OTL type amps, a pure "Power Paradigm" amp that doesn't use NF and that has a somewhat high output impedance will likely choke on speakers that were designed to be driven by low output impe... | |
| Audio Research Reference 5SE reliability Anwar, I checked the MAC web site. Input impedance is 22,000 ohms Balanced and unbalanced. That just 2K ohms over the minimum ARC recommends. If you load any other devices (e.g., subwoofer) to the Ref 5's output, you may overload the Ref 5. | |
| When an amp puts out 90 watts.... Ralph, re your post about 4-16 ohms at various frequencies not being a problem if the tube amp has 10db or high NF seems correct. As you know, I posted links to Soundstage and Stereophile bench tests of the ARC VS-115 and Ref 150 tube amps. Both a... | |
| Audio Research Reference 5SE reliability Anwar, what is the input impedance of your McIntosh MC452 amp? Is it over 20K ohms? |
