| any audiophile guitarists out there? Kijanki, I used to play out with bass a lot. These days, I play out with keyboardshttp://www.myspace.com/thunderboltpagodaThe tracks on the myspace are from live shows a few years ago. | |
| Balanced vs Unbalanced? Herman, look at it this way: a differential amplifier does not care if it is getting a single-ended or balanced input signal. It will act exactly the same in either case. So if the input signal has two opposing inputs that have slightly different ... | |
| Does "perfect alignment of cart" eliminate 100% ? Some arms are more affected than others, yes. Mistracking in the inner grooves might also be caused by the mechanical resonance of the arm/cartridge being slightly too high.Electrical loading of the cartridge can help too.Some preamps will exhibit... | |
| Balanced vs Unbalanced? Rleff, it really depends on the speaker rather than the technology. Its the 'all else being equal' part that prevents an answer beyond that. Either one can be awesome or suck really bad. | |
| 6922 6DJ8 or 12 AX7 tubes better for preamp? 6SL7s have similar gain to 12AX7s. IME they are often prone to microphonic issues and so have to be very carefully hand-picked. Of course in a LOMC phono section *all* tubes must be picked for low noise. It is this reason why truly quiet NOS tubes... | |
| 16-ohm driver question Yes. If your amp was set up for 16 ohms, the output transformer would have less distortion. That translates to greater transparency and smoother sound. You will also get a little more power. | |
| Why not horns? Unsound, I appreciate your last comment. It is where I was for many years, and to this day (and I expect for years to come) I still run into horn designs that are guilty of everything you mention in your first paragraph. When horns suck, they real... | |
| any audiophile guitarists out there? I play a bass guitar- it looks like an acoustic guitar but has only 4 strings. I built up an little amplifier that is pretty fun to play.There's a photo of it at this thread on DIYAudio.com. | |
| Balanced vs Unbalanced? Herman, just for the record, I like SETs a lot myself and have built a number of type 45 and 2A3 based amps.But before we go into that, One unmentioned difficulty is that for everything to work as designed you have to have a circuit capable of pro... | |
| 6922 6DJ8 or 12 AX7 tubes better for preamp? The 12AX7 is great for noise and low distortion, but is bad at bandwidth, making it a poor choice if you want passive EQ. The 6922/6DJ8 has good bandwidth, but the design of the tube is not for audio: while very good linearity, the design is prone... | |
| Why not horns? Herman, I leave the design of speakers to someone else to prevent headaches. I was just pointing out that the crossover can be used to correct time alignment (sometimes this results in the need to reverse the phase of certain drivers as a result),... | |
| Feedback on Classic Audio Reproductions T-5 The last time I heard the T5 was quite a while ago at a show. They are easy to drive, in a lot of cases 60 watts may be all you need. They are 16 ohms so making power with a tube amp is easy with them. The thing is, John has been updating the T-3 ... | |
| Balanced vs Unbalanced? I did forget something- a request. There are those of you here that disagree with my prior post and will have talking points. Please keep them if you can to one talking point at a time, so that we can be clear that they get responded to in a coher... | |
| Balanced vs Unbalanced? Alright, there is a fair amount of misinformation in this thread, and I thought since we essentially introduced balanced line operation to high end audio, I thought I should correct the misinformation herein and explain some of the whys.Balanced o... | |
| small room... tube amp... summer I have a box on the other side of the wall that has the amps in it. It allows very short speaker cables to the speakers, and keeps the heat of the amps outside of the room.I have a customer in Guatemala City who runs our biggest amp (42 power tube... |
