| D class amps with Soundlab speakers For the most part solid state amps do have trouble making power on this speaker. I would not expect a class D amp to have problems with the load otherwise, just that you would want one with a lot of power (600 watts or more depending on the room) ... | |
| nakamichi vs threshold I've heard a good number of technicians comment about that design- as I understand it, it is one of Nelson's earlier designs but due to construction or other factors did indeed have a reputation in the service industry (I ran a service shop for 15... | |
| converting Rega to balanced output? Elizabeth, best I can make out from your post, that scenario will hum. The problem is that the stock arm cable uses the minus output of the cartridge as a shield, so if that is used on pin 3 of the XLR you will have a substantial hum.Its unfortuna... | |
| converting Rega to balanced output? I have done this operation a number of times. The Rega arm is set up with RCA cables coming right out of its base. But if you take it apart, what you find is that there is a tiny dime-sized round circuit board on the other side of that rubber plug... | |
| nakamichi vs threshold FWIW the Nakamichi amplifiers had/have a reputation for being unstable that they had from the very beginning. Its one thing for an amplifier to sound nice, another for it to run reliably from day to day. | |
| D class amps with Soundlab speakers Sound Labs do play nice bass. The trick is if the amp can deliver power into the bass frequencies as their impedance can be quite high. This is why they seem very power hungry if you have a transistor amplifier- an amp that makes 400 watts into 8 ... | |
| Enough SET Power for Rock and Roll I had a set (pardon the pun) of SET 45s. My speakers are 98 db. There was no-where near enough power...So I built up a set of type 45 push-pull amps just for fun. Instead of about 3/4 watt, now I get something more like 5. So about double what I g... | |
| Which LPs are on your permanent rotation? Steve Tibbetts' 2nd LP ('yr') has been stalwart over the last 30-some years as his 4th LP 'Safe Journey'.ELP's 1st LP, self titled (pink Island edition). I seem to never tire of it; same for King Crimson's 2nd LP 'In the Wake of Poseidon', which a... | |
| Anyone listen to Zu Audio's Definition Mk3? As a point of reference in the past the Definition was a 6-ohm load and inappropriate for the Atma-Sphere S-30 although the M-60 was fine with it. Zu offered the Definition in a 30-ohm edition that by all reports was an excellent combination with ... | |
| Hum from both speakers...This is New Please read. That does sound like it could be a ground loop problem, but if so it has something to do with the subwoofer. If you unplug the subwoofer from the wall that should manage the hum.If not, then my 2nd theory is that there is a wiring bug in the outpu... | |
| What determines good distortion? Mapman, the test is simple- put the amp on a speaker load (nearly any load will do) and run the amp up to clipping with the sine wave, and observe the results on a 'scope. Of course others have already done that. Goto Google, click 'Images' then e... | |
| How do we remember 1970s amplifiers? I had a set of Fulton J-Modulars as well. For a long time I ran them with dual modified Dyna ST-70s monostrapped until I got my own amp going. Fulton was a local so I spent time with him at Bob Fredere's house in Minneapolis, which is where I firs... | |
| What determines good distortion? The odd-ordered harmonics (above the 3rd) are used by the human ear/brain system to ascertain the volume of the sound being heard. This is pretty important to know if you want your system to sound like real music rather than a hifi.If an amplifier... | |
| Class A amplifiers - which are considered the best Class A has two modes of execution, A1 and A2. In A1 the output devices conduct all the time and there is no current flowing in the grid circuit (we are talking tubes here). In class A2 the output devices also conduct all the time but there is gri... | |
| Turntable speed accuracy Servo design in a DD 'table certainly includes the expected mass of the platter. If that changes significantly it sill alter the response of the servo; likely to the underdamped side of things. Many cheaper DD tables have a platter that can be rem... |
