If your source puts out enough voltage to drive your headphones, you don't need an amp, all you need is a Passive Attenuator. It can be just a log pot in a box with sockets, or it can be a stepped attenuator built on a 24 step switch. The problem is usually calculating the resistors you need to...

Quote: Originally Posted by Rise To The Top Say if I got SR202's... could I grab 404s later on and use the same amp? You could. But it would be smarter to keep the 202 earspeakers and upgrade the amp to a used Stax tube amp. I have 202 and the 252A, which I bought with the...

Quote: Originally Posted by MaloS Interesting. Although, 900 Vpp does not mean it needs to be 900 V peaks, it can swing -450 to 450. Is that still outside of limitations of 6sn7? What follows is general information and my own opinion. I don't know anything about the prototype of...

I wouldn't try for a formal review. Write down the thing you like best about the headphones you are reviewing, then the next, and so on. Do the same with the things you don't like. Now organize them together in some kind of a logical structure; almost any structure will do, even chaos (for...

Quote: Originally Posted by pembers hello chaps I found your comments very interesting Andre, Im to thinking of getting either an 2050 or 3050 system, and wondered the difference. I hear that between the 303 v 404 there is nothing in it, can the same be said for the 202 v 303? And...
