| Anyone With A Class 'D' Amp Play A 4 or 2 Ohm Speaker? I play them in extended mode. I have a very big room. I would advise caution in extrapolating from the results others report with different speakers!Even with the Scintilla. Not only does the impedance of your speakers go a bit lower than the impe... | |
| Anyone With A Class 'D' Amp Play A 4 or 2 Ohm Speaker? Mitch, are you using the speakers with their "extended/normal" switch in the "extended" position (which iirc seemed to be the most commonly preferred setting), or in the "normal" position?In the "extended" mode the Kappa 9 goes down below 0.8 ohms... | |
| Can a Quality Full Range Speaker be the Limiting Component in a system? Can a quality full range speaker be the limiting component in a system? Hi David,It seems to me that a "yes" answer to your question must follow from the fact that different "quality full range speakers," regardless of how those terms are defined,... | |
| high frequency intermittent noise almarg and or kosst_amojan, or others,Would the copper screening work well as a shield and reject RFI from entering through the glass window? Yes, Jim, I would think that a grounded copper screen would be effective against 700 - 800 MHz, since the... | |
| high frequency intermittent noise ... the frequency my stereo is picking up is in the 700 - 800MHz range. James, check out this link:https://www.fcc.gov/general/700-mhz-public-safety-spectrum-0The band extending from 698 to 806 MHz is used by public safety services, with part of... | |
| Do classical CDs made from early analog tapes sound better on your system than new CDs? Inna, the OP may be too modest to say so, but I happen to be aware that he is an accomplished classical pianist and harpsichordist, whose background includes performances in a number of this country's best known and most respected venues.In the f... | |
| Do classical CDs made from early analog tapes sound better on your system than new CDs? One of the most treasured CDs in my collection, both musically and sonically, is Chesky’s remastering of Jascha Horenstein conducting the Royal Philharmonic in a 1962 (!) performance of Dvorak’s New World Symphony. The original recording was engin... | |
| high frequency intermittent noise Jea48 11-17-2017 ...how about when james1969 used the pro-audio monitors for the test. When he hooked them up he heard the same RFI noise. Just a guess the amps are SS. Yes, I had thought of that, and the fact that the same noise occurred with bot... | |
| For tube sound, which is more important: preamp or power amp? Regarding the statement by Mr. Carver about the 50+ year longevity of the power tubes in his amplifier, I would point out that in general there are statistical approaches that are commonly used in deriving published MTBF (mean time between failure... | |
| Low heat alternative to FIRSTWATT J2 ? Kosst, good points in your response to my post. Thanks!Regards,-- Al | |
| high frequency intermittent noise James, searching at eBay for "RCA shorting plugs" (without the quotes) will lead you to a number of sellers offering them at low cost.Good point by Ralph (Atmasphere) re the possibility that the amp doesn't provide grid stopper resistors in its de... | |
| Let's talk power cords In the many threads that have addressed this subject over the years here, IMO the best and most informative single post that has been made is the following one by Atmasphere, which I'll quote in its entirety from the following thread:https://forum... | |
| PADIS vs Furutech fuses Toolbox, nearly all preamps, source components, and amplifiers that are biased in class A draw essentially the same amount of current and power all the time, as long as they are in an operating mode (as opposed to a standby mode). So whether or no... | |
| Does a new cd transport require break-in time? Well, if the gentleman’s response is accurate it would mean that the "<75 ohm" spec is a misstatement. So if either of you chooses to follow up with him, you might ask "then why does the spec say <75 ohms?"Best regards,-- Al | |
| Low heat alternative to FIRSTWATT J2 ? I have also heard that same friend's DIY build of the First Watt SIT amp. That was a really nice sounding amp too, but, I suspect it puts out even more heat than the J2. The J2, SIT-1, and SIT-2 all have specified power consumptions of 200 w... |
