Dynaudio Evidence Temptation and tube amps? Thanks to all, decided to buy my buddies Martin Logan 13A's. Running from the 4 ohm tap to minimize the impedance issues in the higher frequencies. If you wind up with the highs sounding rolled off, you can correct that using a set of ZEROs. T... | |
Passive vs Active...Again! Maybe some Open Baffle Speakers would work. I believe they work up against the walls. @high-amp Just so you know, this statement is false. Open baffle speakers need to be about 5 feet from the wall behind them (like any speaker with rear-firing... | |
SET the best? This is issue I see today with SET in general, some of these guys run higher plate voltage then output tubes can handle, too many instances of premature tube failure. People too often blaming tube manufacturers. Prior to purchasing any SET, I'd r... | |
Analyzing Balanced versus Unbalanced Amplifiers--Difference in sonic quality? My point about balanced cabling is that most Class A/B amps have balanced wiring internally due to their construction. This Technics is not a D-Class amp per se because it doesn't convert analogue signals at their entry. Thus, there was no need t... | |
Ok to substitute 12AX7 for 5751 tubes in CJ Amp? @prof A 12AX7 is a poor substitute. The 12AT7 has similar amplification factor but vastly different plate resistance (much lower). Whenever a tube circuit is designed, hopefully the circuit is optimized for the tube in mind. When you put someth... | |
SET the best? I was refering to general charachertistics f the 845, . I’ve read good things about the 2A3,, then here we read the 845 is simply gorgeous. Another comment likes the 300 as driver stage tube,whereas my tech says avoid 300B in any part of the des... | |
Passive vs Active...Again! Just a side note, I had some Martin Logan Spires in a very similar style room, that was much larger with little acoustic treatments and they sounded pretty good. But in this house I don’t have the room to pull the speakers 3 feet of the back wall... | |
McIntosh- Sweetest, Smoothest sounding Solid State ? Who cares? Transparent is the goal. It is, but if the amp is not smooth that is an indication of distortion. Its hardly being transparent at that point. This is only slightly off topic, but what sonic coloration does an autotransformer imp... | |
SET the best? how would you describe the sound of a 845 tube? You can’t- any more than you could a 300b or type 45, because the output transformer and the individual tube’s match to it plays such a critical role. People often say the tube has a certain soun... | |
CUTTING DOWN A TONEARM CABLE I read/feared tales of ideal length for tonearm cables - something to do with capacitance @lohanimal A good tonearm cable will be low capacitance. But I would not be concerned about shortening one, because when you reduce the capacitance (which... | |
Sub for single-driver desktop speakers I've played with single driver speakers a lot, but not had them be as satisfying as a 2-way or 3-way, depending on the size of the speaker. To really get the sub to blend its a good idea to keep its output below 80Hz. Otherwise it starts to attra... | |
SET the best? I can't imagine any benefits from class D for high sensitivity speaker. I can!! Low noise so low its hard to hear even with your head in the mouth of the horn- and greater detail/better 'focus' so images in the rear of the sound stage are easie... | |
SET the best? There are so few threads focused on SET amps....Is it too much to ask that the AGD and GAN and Class D discussions be moved to their own thread or one of many already in existence? @david_ten There are also a good number of SET threads. The com... | |
SET the best? It pointed out that “all” other current GaN based amps use existing modules with chips that are currently used in non Audio devises like power chargers. @mglik If he's getting semiconductor devices made for him I can see that happening. Usually... | |
SET the best? The GaN module used is the only such chip developed specifically for Audio. AGD has just come out with a stereo amp called the Tempo. It uses a aluminum chassis cut from a solid billet. It is a more conventional design without the “tube” but uti... |
