| MC352 into varying-load speaker? Ron: Thanks again for all of the info. This has been very educational for me, at least pertaining to Mac products, design philosophy and implimentation. I do have to take issue with some of the comments that you made and a few more questions if yo... | |
| Home Spindle Lube Test Bob: I think that Rockvirgo has demonstrated just the opposite of what you stated i.e. "all engine oils are overkill - even olive oil will do". There's obviously a very big difference in the ability to lubricate and reduce friction between the ite... | |
| Room Acoustics Mprime: As it is right now and if properly done, treating the room acoustically provides far more benefits than doing so electronically. This is not to say that electronic correction doesn't sound good, but that i don't think it sounds "as good" o... | |
| MC352 into varying-load speaker? Ron-C: Thanks for the education and background. I learned something today. I wasn't aware that this was basically an amp that was bridged internally. You made mention of the fact that the autoformer is linear to 100 KHz or so, which was wider in b... | |
| Will this isolation transformer limit power draw? If the amp is 19 years old, it still has at least a few months left of Bryston's 20 year factory warranty. In plain English, your amp has a problem. Call up Bryston, give them your serial number and see if it is still covered. If it is, make arran... | |
| Good Better Best Interconnects Phasecorrect: The bass with the MI-2's can be as good or bad as your amplifier / speaker interface is. Given the low impedance of the cables themselves, they don't inhibit power transfer, so the amp can load into the speakers the best possible. Th... | |
| Sony XA7ES is this still a top notch player? The upper model Sony units provide an excellent platform to build upon in terms of modifications. As mentioned though, these units are getting up in age and you may want to secure some of the basic parts should you choose to invest in such a unit.... | |
| Shure V15VxMR to be discontinued Shure isn't an "audiophile" oriented company. If they say it is going to be discontinued, you can bet your bottom dollar they are going to pull the plug. If Shure actually were an audiophile company, they would discontinue this model and then come... | |
| MC352 into varying-load speaker? Aball: Has Mac always used a bifilar design or is that what they've gone to on more recent models? While i saw the test results / bandwidth on one of their more recent models, and it looked pretty impressive for an output transformer coupled model... | |
| Will this isolation transformer limit power draw? El: That's a good point about the "down time" on a sine as it is crossing over. Forgot about that : )I can also see how a square wave would be FAR more efficient due to the longer duty cycle and more consistent peak to average ratio.While it is tr... | |
| Weather-induced amp performance variation If you leave a high bias amp turned on, the device tends to stabilize temperature. It will not shift measurably unless there is a measurable shift in room temperature. Most common amps that are biased for lower level Class AB operation will underg... | |
| Room Acoustics Most "mild" room treatments utilizing thin layers of foam and / or "stuffed" cloth materials, etc... are actually very non-linear in their absorption of frequencies. I commented on this many, many years ago in the Agon archives and posted links to... | |
| Will this isolation transformer limit power draw? An outboard bank of caps is FAR less effective than capacitors placed as close as possible to the output devices. That is, as far as storage devices go and minimizing sag on the rails.As far as the 60 Hz voltage vs the rail voltage goes, the 60 Hz... | |
| FABULOUS guitar wanking Duane: Somehow, i knew that this guy was going to be "old hat" to you : )Isellstuff: If you don't mind, what clubs in IL does he tend to play at? I'd love to see this guy live, just to see if he can duplicate what he does on record. I've seen WAY ... | |
| Amplifier Speed The time it takes for the signal to travel from the input to the output would be dependent on the length of the circuit and the velocity of propogation through the circuit. This is technically referred to as Td, hence my comments about the lack of... |
