| Audio Research preamps EXCESSIVE OPERATING COSTS Very expensive when replacing 8 tubes.@emergingsoul Its unusual to have to replace all the tubes at once! Tubes have really variable service lives. Some will go a few hundred hours and others will go 20,000 hours. | |
| Are there any tube amps that don't give off any--- @daveyf If heat really is the deal (and installing inexpensive venting is out of the question), then you might consider a class D amp, as they run the coolest of any kind of amp. There are some class D amps now that rival tubes for smoothness and ... | |
| How to judge a preamp's sound @hilde45 FWIW even a cable and no preamp at all has a sound unless you jump through some hoops to prevent it doing so. It helps to have recordings with which you are familiar. I use recordings I made myself (and have the master tapes) so I know ho... | |
| Slight hum coming from preamp/amp My surmise is the hum has something to do with the computer but if you only hear it with your ears near the drivers of the speaker its absolutely no concern whatsoever. | |
| Audio Research preamps EXCESSIVE OPERATING COSTS The tubes only cost that much when you get them from ARC. They are in sockets for a reason- they are considered 'user replaceable' which means you can buy tubes from the Tube Depot or the like and spend considerably less! | |
| Highest BUILD quality tube amps? IMO/IME building a power amp, especially a tube amp, is best done point to point. This ensures that the amp will have the longest life. But I also find it important to have a nice build quality and appearance internally, since its actually easier ... | |
| Pass Labs x250.8 vs tube amps The Sound Labs are a different sort of beast. Like most ESLs, they don't work so well with amps that can double power as impedance is halved, since the Electrostatic principle doesn't rely on a driver in a box...The impedance curve of the speaker ... | |
| The CJ Premiere 12 was the best vintage tube amplifier ever. I find this hard to believe. The Harmon Kardon Citation 2 had/has wider bandwidth and lower distortion (by half). Of course it dates from 1959-1960 so is a good 30 years older, but if properly refurbished with new filter capacitors in the power su... | |
| Are there any tube amps that don't give off any--- Remember Ralph, hot glass looks just like cold glass. This is from personal experience (goes for metal as well).True, but this comment (taken out of context) was part of an explanation of how in most cases the filaments are not why tubes run so ho... | |
| vinyl versus digital redux Atmasphere! I have two original copies of It's a Beautiful Day! I loved it so much I bought another copy worried I would play the one to death. Finding the original Columbia of that is no easy task. It sounded great, and people played them to dea... | |
| Nad 6100 Cassette Deck plays a few seconds just fine then stops Take a look at the tape counter. Its common (and not saying that this deck was done this way) that if the tape counter stops moving, the machine automatically stops. This is done to prevent it from eating tapes. The symptom is that of the take up ... | |
| Why I enjoy my Luminous Audio passive unit, vs an additional gain stage ( preamp ) I have had 100% true/dif balanced systems for decades (typically with a balanced preamp), but find it super easy to hear differences in XLR cablesTry setting the input impedance to 2000 ohms in your amp. I doubt that Oppo would drive that, but i... | |
| Why I enjoy my Luminous Audio passive unit, vs an additional gain stage ( preamp ) @mrdecibel Insist that if there is a balanced connection, that it support AES48 in all aspects. | |
| TONEARM DAMPING : DAMPED OR NOT ? ? USELESS ? ? WELCOMED ? ? Unfortunatelly audio analog is not really a science and do not exist inviolable rules.I don't find this to be true, nor do I worry about being a minority in this regard. There's a lot of 'by gosh and by golly' in this hobby. | |
| Anyone hear Classic Audio T9? Then there's the question of how does the acoustic lens sound compared to the tractrix horn? The lens seems to have a harshness (this entirely IMO) compared to the tractrix horn. If you're interested in the T-9, by all means, call John and talk to... |
