XLR vs RCA
I am with Warrenh. Even though Audioengr's points are valid, the last one is the biggest concern with balanced systems, the impossibility of designing a truly balanced system.A system that is balanced from beginning to end is actually two chains o... 
Low output MC - Math Question ??
voltage gain = inverse log (dB gain / 20)inverse log X is 10 raised to the power of XYou are looking to make up the difference of 15dB from the 80dB MC stage to the 65dB MM stage.15dB divided by 20 = .75take the inverse log of .75 = 5.6.3 mV times... 
Helpful Hint When Cleaning Records
Oh, mine has a cork mat. I thought they all did. 
Helpful Hint When Cleaning Records
Why don't you clean the mat on the machine just like you would clean a record? 
Clearaudio MAGIX Magnetic Isolators ?
I agree with TWL. Another point is the claim that these devices "truely stop all resonence sound from your equipment, which actually is suspended on air."Yes, they are suspended in air with no mechanical connection to the platform. But they are no... 
Starting Over
There are a variety of 2A3 and 300B integrated amps that can be had for around $1000, a set of Lowther medallionsfor around $2500 with nice drivers and a Toshiba sd9200 (DVD-A, CD, HDCD)for less than $800. Add a sub and you have a nice system for ... 
What do these tubes sound like?
I agree. Of course I have no way of knowing whether the Duetto can actually do 15 Hz because I have Lamhorns with DX3 Lowthers that don't play much below 60. I have them supplemented with an MBL sub that integrates very well and gets me pretty fla... 
I just installed NOS tubes?
I take it from the tone of your post that you are unhappy with the new tubes. It may be that you were sold tubes that are worn out or are fakes. Some people that claim to sell NOS(new old stock) are actually selling WOOF (worn out old fakes). The ... 
What do these tubes sound like?
I completely disagree with the assessment of the 300B. “Treble is severely rolled off. As are the lower frequencies, which are the very definition of loose.” The performance of a tube at these frequency extremes is a function of amplifier design a... 
My Levinson doesn't like the juice
I had a similar problem with an amp that hummed when the line voltage was too high. I called the power company and they came out and retapped the transformer out on the pole to solve the problem. The power company has to adjust your line if it is ... 
Speaker match for 75 watt Tenor amps
I am so proud to have participated in the most stupid thread on this forum. I especially enjoyed Natalie's advice to "stay as far away from a Horn as is humanly possible." I own Lammhorns and have heard a variety of horns in a variety of systems. ... 
Speaker match for 75 watt Tenor amps
How about the 15 watt Tenor amps and a pair of Lamhorns. 
Shipping to Portugal
Depending on how big it is you can probably mail it pretty cheaply since it doesn't weigh that much. Look Here 
Specification of 5U4C and 5Z4GT
The difference between a 5Z4G and a 5Z4GT is the shape of the tube, they have the same specs. My tube manual does not list a 5U4C, only a 5U4G. If it is a 5U4G, then the specs are quite a bit different than the 5Z4G. The 5U4G draws 1.5 times more ... 
Can you cancel an auction?
There is an option for the seller to cancel until the minimum has been bid. That option then disappears from the seller's menu. That is not explained in the rules but that is the way it works. Here are the rules.
