| BUY Bryston!!!!! I too have had an exceptional experience having a Bryston product serviced by their Vermont facility.A couple of years ago my Bryston CD player developed a problem with the display. Bryston repaired it by replacing the entire front panel assembly,... | |
| Measuring impedance with multimeter While the Elac Debut B6 has a specified nominal impedance of 6 ohms, it can be seen in Stereophile’s measurements that its impedance is above 10 ohms at all frequencies above 500 Hz, and is above 20 ohms at almost all frequencies above 1 kHz! 6 oh... | |
| Measuring impedance with multimeter The multimeter measures the speaker’s impedance at zero Hz (i.e., DC). That reading will usually be significantly lower than the impedance at audible frequencies.Not to worry!Regards,-- Al | |
| My Long List of Amplifiers and My Personal Review of Each! A symphony I recommend to those who have not had much exposure to classical music is Prokofiev's short (~ 15 minute) "Classical Symphony," a work that IMO is just about impossible to dislike. Here is an excellent video of an excellent performanc... | |
| Magnavox or RCA tube amp My instinct would be to go with the RCA. Back in the day they made some nice little 10 watt or so amps using push-pull 6V6 tubes in their output stage. Around 1990 I acquired a vintage RCA mono integrated amp that was either the following model ... | |
| DC Offset Blocker/Killer - where to buy in the USA That all seems perfectly consistent with the explanation I proposed in my previous post, Jim. The hairdryer draws considerably different amounts of current in the positive half-cycle than in the negative half-cycle. The resulting DC offset corresp... | |
| DC Offset Blocker/Killer - where to buy in the USA If Al is still following this thread I am sure he will have a better technical answer. Not necessarily, Jim :-)Your finding that having the hairdryer plugged into the outlet where the measurement was taken resulted in a DC offset of around 730 mv,... | |
| Which area of components to spend the most $ on? Boy I was wrong all my life! While there are exceptions of course, for a given level of quality there will tend to be at least a loose correlation between the cost of a speaker on the one hand, and the deep bass extension and the maximum volume it can provide with reasonably... | |
| Different types of cable for bi-wire There might be an issue, depending on the impedance characteristics of your speakers and on the length of the cable. For example, the combined resistance of the two conductors of a 10 foot 26 gauge silver cable is around 3/4 of an ohm. That is abo... | |
| Is DEQX a game changer? Hi Steve,For the speaker calibration measurements what I initially tried was placing large sound-absorbent panels behind and to the sides of the measurement mic, with each speaker having been moved to the center of the room for purposes of that me... | |
| My Long List of Amplifiers and My Personal Review of Each! To add to the foregoing comments about the benefits a preamp can provide, without a separate preamp some DACs will not be able to drive some power amps to full power. The Lampi Pacific is a case in point, when paired with some of the power amps th... | |
| Help! Power question As Cleeds alluded to, it may be helpful to indicate which specific Furman model you are using.And if it is one of their models which provides "current reserve" at some of its outlets, that are intended for connection to amplifiers and subwoofers, ... | |
| Will a MC phono preamp overload and distort with a higher output MC cartridge? The phono stage is spec’d as having a gain of 650 (which btw corresponds to a gain of 56.26 db), and as having a maximum output capability of 3.2 volts.3.2 volts/650 = 4.9 mv.So an output from the cartridge of 4.9 mv or more would overload the pho... | |
| DC Offset Blocker/Killer - where to buy in the USA P.S. to my previous post: I didn’t mention the units that should be used for R and C in the various calculations. If R is expressed in ohms and C is expressed in Farads, the calculation described in my last paragraph will provide an answer express... | |
| DC Offset Blocker/Killer - where to buy in the USA Hi Jim,They both appear to be reasonable values for this purpose. The 10 uF/100K combination will charge up to the final value about twice as fast as the 22 uF/100K combination, which isn't important, but it won't be down quite as far at 60 Hz as... |
