| Vintage Tube Amplifiers - Any good? Some consoles were pretty good. Many were terrible!But there are plenty of vintage amps that sound great on modern speakers:Harmon Kardon Citation 2, Dynaco St-70, Marantz model 8 and model 9, Fisher, HH Scott and so on. Any of them would need the... | |
| Horns: Why don't they image well? Partly correct, but for many years horn systems have included "phase plugs" or their equivalent to keep horns from "beaming" high frequencies.This statement is problematic. Phase plugs are used to prevent cancellation at higher frequencies, thus... | |
| Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other??? You can buy your own EPC GaN boards from Digikey, and yes they operate with no heatsink. Because EPC’s Steve Colino said to me, (and I posted up his email), they are at 600khz switching speed, you can increase that to 1 or 1.5mhz as Steve said,... | |
| Why Power Cables Affect Sound @mitch21. What characteristics of a power cord would affect voltage (i.e., cause a voltage drop) - is that primarily a function of resistance and wire gauge, or something else, and 2. What characteristics of a power cord would affect bandwidth? ... | |
| Which Class D Amplifier? PS Audio, Ghent, Nord, Merrill or other??? The Class-D is just going to be a money spinner for him, he buys the modules does a small mod so it can be said to be better, throws in in a box, and there’s his beer money. @georgehifiJust for the record, this statement of yours from the beginn... | |
| Why Power Cables Affect Sound I’m just generally curious what is going on scientifically speaking. Furthermore, once we understand the phenomena then we can design and tweak to produce the results we want. For example, maybe the gauge of the copper fully explains the effect. I... | |
| How do you properly set up a horn speaker ^^ +1 | |
| Does anyone care to ask an amplifier designer a technical question? My door is open. But other than possible tube noise floor raising...is the actual sound likely to alter in any way as tubes age?Yes. If their transconductance falls below the minimum values, the performance will suffer and can affect things like bandwidth, distor... | |
| Increase total Speaker Impedance -- Potential Solution Question is will the somewhat high output impedance of the amp still affect the bass negatively?Probably not, unless slightly enhanced bass is seen as a negative. It won't be by much though.Overall impedance showing in my multi-meter is 4.1 ohm.Th... | |
| Doug Schroeder Method, Double ic Atmosphere....kindly post your findings.....I have a balanced system, am using Doug's system with no Y connectors made by AudioSensibilies, and have experienced a great improvement from regular XLR'sI will. BTW I'm pretty sure the Aesthetix prea... | |
| Linear tracking turntables, whatever happened? Understanding these design differences will go a long way towards setup of both tonearms. If anyone is toasting carts on an ET2 they have no idea how to set it up. Sounds to me like your dealers were Personality Type B...8^0. @ct0517Looking back... | |
| The Future of Audio Amplification Nobody cares about class T?People consider class T as in the same category with class D?Yes. 'Class T' is a trademark. | |
| Doug Schroeder Method, Double ic Right Doug....2 -1 meter pair (phono to preamp, silver disc player to preamp) and 1- 5 1/2 meter pair from preamp to amp. Still not broken in.....interesting the 1 cable that is oldest is phono to preamp.... phono sounds WAY better than CD. Al... | |
| The invention of measurements and perception @erik_squires If you can find a copy of the Radiotron Designer's Handbook, 3rd Edition (published in the 1930s) its pretty evident that we've known for the last 80 years that the various harmonics are treated very differently by the human ear. Yet... | |
| Linear tracking turntables, whatever happened? ok - I will rephrase. The best linear tracker tonearms use the same force for movement across the record as a pivot arm - the groove. @ct0517That suggests the possibility of an air bearing. I don't have a business relationship with Triplanar, just... |
