Preamp Deal of the Century
Chelvam, I've seen photos of the insides of 2 Suprateks (one photo is in a 6moons review). In both, the filter caps in the power supply were not secured by any hardware, instead were simply glued to the inside of the unit. This is a Bad Idea even ... 
Preamp Deal of the Century
I was under the impression that Supratek had folded some while back- maybe a year ago or more. If they are back, I certainly hope that the new product does not have the same construction technique of using glue to hold components in place (as this... 
CAT JL-3 Sig Mk2s direct from Wadia 781i?
Gnsc, 4.5V is the absolute **maximum** that a DAC should produce for 0VU on the CD. We've seen players that make as much as 15 Volts; even 7 Volts is -no other way to put it- retarded.Amps that need over 3 volts are unusual to say the least, conse... 
CAT JL-3 Sig Mk2s direct from Wadia 781i?
If you are not playing vinyl, you can fine-tune most Wadias to work directly with your amp. The issue is that most DACs and CD players make **way** too much output voltage, causing the user to run low volume control settings. On a lot of DACs, thi... 
Which speakers are higher efficiency?
Most 300b amps have 7 watts output or so. Is your amp an SET (and therefore class A2) or is it push-pull?If an SET, it is essential that the speaker have higher efficiency. I am running a 30-watt amp on speakers that are 98 db, in an average size ... 
Which MoFi and MoFi UHQR LPs?
The Mobile Fidelity thing, like any other records, are fueled by taste and rarity. Usually they are not better than the originals, but sometimes the originals really sucked or are so rare that they essentially don't exist.A good example of that la... 
What do you see as the downside of tubes?
Eldartford, digital modeling amps have been around for years in the guitar world. As far as I can tell, people only play them out of desperation as they are a far cry from the thing that they are trying to model, i.e. a Marshall Plexi or Fender Tw... 
The disappearance of the traditional amplifier
Kirkus, if you can, try out a set of High Emotion Audio S-7s for near-field. They will give you very reliable information about what is going on in the recording- and no lobing effects if you happen to be off-axis. They have the widest dispersion ... 
What do you see as the downside of tubes?
Actually, Carver showed that an amp could be *modeled*, but even in his tests the modeling did not match the actual behavior of a tube amp.Mapman, here are some primary differences. 1) Tubes are often much more linear than transistors. Triodes are... 
What do you see as the downside of tubes?
We put a Standby feature on our amps so that you could keep the amps warmed up 24/7 if you wanted to- and rated the amps accordingly. The nice thing about tubes is that if you want the system warmed up properly, it only takes about 3 hours, where ... 
Choice: Avantgarde Duo Omega or JBL K2 s9800
Triode, what is important about that is that the speaker does not have to be out in the room to image well. 
Choice: Avantgarde Duo Omega or JBL K2 s9800
Art80342, I spent about a week listening to the K2, in a very controlled environment. My opinon comes from listening to both speakers, both with amps that I know and also those that I do not. Either way, the K2 is an easier setup (it can be close ... 
Joule Electra or Wolcott Tube Amps, or...?
Outlier, mbls have low efficiency ratings as they radiate to 360 degrees, which means that the mic making the measurement will not pick up all the energy the speaker puts out.The result is that if you have the speaker in a room, the radiated energ... 
Choice: Avantgarde Duo Omega or JBL K2 s9800
Art80342, this one is easy: go with the JBL! The K2 is an excellent speaker well beyond the Duo, though less efficient. You will have plenty of power though. 
What do you see as the downside of tubes?
Raquel, just a FWIW, we probably have as many tubes in our amps as anybody, but they are autobias and hold together quite well, even if a tube fails. Having a lot of tubes does not have to be a pain in the neck if the amp is designed properly.
