| 24 feet DIN to XLR phono cable for Graham Phantom? If the preamp accepts the phono signal differentially, then you stand a very good chance of making this work, especially if the cartridge is loaded at something less than 600 ohms.This will create a low impedance balanced line, and will be quite i... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade It is possible that the power supply ground of the speaker is somehow also connected to the speaker terminals. That could cause some amplifiers to be ground-looped. A continuity test between the ground pin of the AC cord and the speaker terminals ... | |
| My Final Amplifier Purchase - What Would You Buy? Hello Nightfall, I don't think I recommended a particular speaker, but if I did I would expect that Audiokinesis would have been on the short list. Duke is an outstanding designer and also easy to deal with.Other matches with the S-30: Merlins, ZU... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade This is *starting* to sound like the preamp is off the hook. Did you make sure a jumper is there between pin 1 and 3 of the XLRs? If that is missing it may not matter what the source is.A balanced amplifier has 2 inputs: inverting and non-invertin... | |
| Building balanced interconnects--ideas Jafreeman, seems to me that you have a misunderstanding of what balanced operation is all about.The origin of the technology was to reduce the effects of cable length; essentially, its introduction made transcontinental and inter-continental phone... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Yes- if pin 3 is not tied to pin 1, while the RCA is in use, the amplifier will buzz whether the preamp is on or not, and whether its plugged into the wall or not. Also, FWIW it is not uncommon for a preamp to buzz if it is not powered up. The rea... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Hi Grannyring, if the the chassis is grounded to the middle pin of the IEC, but there is no resistance (open) between the RCA ground and the chassis, then the chassis can act as a sort of antenna- and thus can can buzz.A resistor of about 100 ohms... | |
| Benz cartridge phase? Air is non-linear, but this affects air pressure with respect to altitude. As long as your altitude stays constant while the speakers are moving in and out, you should be OK :)Absolute phase *does* make a difference though- we have had a phase swi... | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade We had a Dude in here for repair a while back and found that the ground setup was peculiar. In a nutshell is would not pass UL/CE certification. I understand later units are grounded differently.I think there are several things going on with the v... | |
| My Final Amplifier Purchase - What Would You Buy? Doug is correct in that the S-30 is mismatched with your Silverlines. The Silverlines are, for the most part, based on the Voltage Paradigm and the S-30 is based on the Power Paradigm. IOW the Silverlines want an amplifier that has constant voltag... | |
| Pass XA Monoblock Amps with Audio Research Preamps If the input impedance of the amp is less than 30K, ARC preamps will tend to be bass-shy. There was a thread about this just a few months ago. | |
| Amplifiers:A Keeper for Life. Do you know of one ? Anybody listed all the amps to keep for life? | |
| TRL Dude or Joule 150 MKII for Major Pre Upgrade Mitch2, as much as I think you should be buying my preamp :) instead of the Dude, I am sure the Dude can work with your amplifier. The problem is that the adapters you were using were not wired right.The problem is that pin 3 of the XLR was left f... | |
| pass labs xa30 to valve amplifier. James123, a preamp that supports the balanced standard is my suggestion. The ARC is one that does not. The balanced standard (what created balanced line operation) is supposed to make the system immune to the quality/length of the cable. If the pr... | |
| I've narrowed it down... Every bit of audio equipment ever made has warmup times at least that long. Not that you can't enjoy it long before that. Many years ago when I still ran transistors, I had to leave them on 24/7 so they would sound their best. It took them a week ... |
