| MBL 101 (~1990) - amp suggestions. Also explains why Aleph 4 was not happy, it can live with 4 Ohm, but not with 2 Ohm.So ML 23 is a decent match, and an amp doubling output down to 1 Ohm could be worth a try.What is important is that the amp be able to act as a voltage source. It ... | |
| The Hifi Trajectory Of Class D Amplifiers Its been interesting to read this thread after several years. In only 4 years since this thread was started we see that class D has improved quite a lot. This fact is a simple proof that the technology wasn't (and likely isn't now) mature. We deve... | |
| Power Amp advice atmasphere: Thanks for the encouragement. 3 days and still silent. Yes I am still contemplating an upgrade. Before putting the HCA on the market, though, I think I will have it recapped, as a visual inspection shows signs of a need.I presume, g... | |
| Reel to reel Grand Master shows up in the manual as 2 Bias, and 2 EQ, the same as Benjie recommended.All the new tape formulations are set up so you don't have to tweak the bias or EQ. The Ampex Grand Master became the gold standard in the old days so its a g... | |
| MBL 101 (~1990) - amp suggestions. This speaker is not that hard to drive; its efficiency appears low because most of the sound does not get to the microphone that is placed only one meter away.You can drive it quite successfully with tubes. But a lot depends on the size and liveli... | |
| AYRE VX-5 TWENTY- WHICH TUBE PREAMP MATCHS I assume you mean by “balanced standard” that there are conpanies that incorporate XLR jacks but that they have single ended circuitry, as opposed to fully balanced designs such as those by Ayre and Aestestix?Actually no. A component can suppor... | |
| ***Is It Me Or Have Todays Modern Tubes Gotten REALLY REALLY Good*** We designed all of our stuff to work with the garden variety of available tubes. Why saddle the customer with the need for a tube that is difficult to get?My experience has been that the Chinese signal tubes are pretty good but for power tubes the... | |
| Power Amp advice FYI the hum was not coming through my speakers. It appears to be solved, at least for now, by tightening all the screws I could access without dismantling the innards. I suspect a sympathetic resonance of some stripe. I also suspect it will re... | |
| Help me rebirth my old turntable Atmasphere: thank you for your additional input. How difficult is it to set up a new cartridge? Thanks again you have been very helpful.I am certain my local dealer would lend me a better phono preamp, but right now my system sounds a little... | |
| Reel to reel This is the tape I'm purchasing; https://www.atrtape.com/products/mds-36-14-x-3600Now I'm trying to figure what bias and equalization I set on the RS1506 for this tape?If you've been using Ampex Grand Master 456 this is a really similar for... | |

| Bias adjustment on solid state amplifiers If your amplifier is in for service, the bias is a thing that should be checked by the service technician (and its very likley that the technician will have to check it anyway if the service has anything to do with a damaged output section). Its n... | |
| AYRE VX-5 TWENTY- WHICH TUBE PREAMP MATCHS In order to really get all you can out of the amp you do need a balanced preamp as you've already surmised. But what most people don't realize is that there is a balanced standard; and that this standard is there to prevent ground loops and also p... | |
| Is there an affordable long run XLR preamp to amp cable out there? Atma-Sphere and BAT opinions are of little value unless you use their equipment.That is not entirely true. Some high end cable manufacturers obtain Mogami wire and re-brand it. The wire is oxygen free and the dielectrics are polyethylene; pretty n... | |
| Help me rebirth my old turntable i don’t understand why it doesn’t sound better unless it is not set up correctly or the needle is worn out. I probably will need someone with more expertise in turntable setup to take a look at this and give me an idea of what my next step sho... |
