| Upgrade path...Need suggestions Yes- tube amps sound more powerful than a SS amp of the same rating. There are a few theories why this so, but the jury's still out. With your budget it's going to be hard to get into a painless tube amp(or monoblocks) with the power that will fee... | |
| Upgrade path...Need suggestions Oh- And you asked about if tubes are a hassle? These PrimaLuna pieces eliminate the bias adjusting, and even feature a soft-start circuit to enhance your tube life. Power requirements: Your Gallo's aren't extremely efficient. How loudly do you lis... | |
| Upgrade path...Need suggestions Look at this stuff, and read the reviews: (http://www.upscaleaudio.com/view_category.asp?cat=96) There are bound to be some on this site used at some point. Any effort you put into dealing with tubes is worth every moment. That's IF you love the s... | |
| New Tube Owner Sometimes a tube may have an internal short or bad connection. A cold solder joint to the tube socket could cause distortion/noise. Any of those problems could potentially be corrected by manipulating the tubes as you did, though it would be a tem... | |
| Bose 901...really First of all: OOPS!! I've been calling the pro speaker the, "801." Shoulda been, "802." To answer your #1) Sure- they've corrected the SPEAKER for freq response(in an anechoic chamber), and generated all that IM distortion in the process(very meas... | |
| Isolation Devices for Digital Determine the weight of you CD unit. Install six Vibrapods (the correct model for your weight of course) to the bottom plate of the player(3 in front/3 in back). Find a piece of Dupont Corian 1/2" thick and the same dimensions as your unit(1/4" sa... | |
| CAL Alpha DAC: Stock vs. 24/96 upgrade The following webpage contains a chart that will tell you what to expect from some popular 12AX7 varients (https://www.tubeworld.com/12ax7.htm). I don't like the Btitish coloration of the Mullard CV4004 personally. My favorite was the Telefunken r... | |
| Bose 901...really You're right about the 801 appearing to be a 901 turned around. The interesting thing is: The 801s have no speakers firing at the back wall(8 drivers, total). That means NO reflected sound, ONLY direct. Their operational concept is the exact oppos... | |
| What does more power do for Magnepans? Pa1- I really do think you will be surprised at how relieving your amp of having to reproduce bass/mid-bass can clean and open up your overall sound. Can you find a dealer that will let you audition one for a week or better? That would give you ti... | |
| What does more power do for Magnepans? Your 9200 has pre-outs and 200wpc. If you were to purchase a Plinius P10(also 200wpc) you could bi-amp very simply. Magnepan offers an optional bi-amp x-over for the 3.6/R, and I'll bet one is also available for the 3.5. You might give them a call... | |
| Bose 901...really It's been my experience, and my point in this discourse, that they have never sounded like live music by any stretch of the imagination. That(live music) is my reference, and will always remain so. I'm much more a sound technician/engineer than an... | |
| What does more power do for Magnepans? For an understanding of audio output in db, and power requirement, read this:(http://www.axiomaudio.com/power.html) It would be nice if doubling the perceived sound only required doubling the power. The least I've powered Maggies with was a slight... | |
| Tube rectification If the rectifier circuit does not have a feature to slow the high voltage from coming up to full: The life of your tubes will be severely shortened. A tubed rectifier circuit allows the tubes to slowly warm up to full operating temps. Because ther... | |
| Bose 901...really I don't think I've read any ratings on those smallish woofer systems that claim much below 40-50hz. Nothing in what I consider the bottom octave. And you are absolutely right on two counts: they still beat their hearts out trying, and that's why s... | |
| Bose 901...really But none of those current speaker designs are trying to reproduce everything from 20Hz to 20kHz with that same one driver. The laws of physics just don't allow it without distortion. Perhaps one day the 901 will be produced with a cone than acts a... |
