AKG K450/K460 DO NOT BUY

by  •  • 0 Comments

These headpones sound great. But the cables break very easily. Both the supplied cables broke within a month. I’ve read reports on the internet where many people complained that they had 4 cables break in a year.

Surely a company like AKG should be able to fix this.

I recommend that you do not buy ANY other AKG that uses those crappy 2,5mm bayonet fixing. Because that means you can’t even fix it yourself.

I’m sorry Quincy Jones that I’m knocking headphones that have your name. But the cables do suck and folks buying these things should be warned.

6V6, Linestage preamplifier, Single Ended

I’m building my 4P1L linestage on a traditional wooden box with aluminium top plate. This takes time. And even though I have been without linestage for YEARS. I started getting impatient. And wanted to build something quickly. But not so quickly that it would not be fit for permanent use in my main system. The “big” bottle preamplier “concept” has intrigued me for a while now. There are so many who say it is a waste to use a power tube as a preamplifier tube. Who cares in the case of us the diy audio crowd?

So in came the IKEA tray. Which is handsome enough to be used as a chassis. I then scrounged all kinds of spare parts. And started drilling. The IKEA tray is so thin that it is easy to drill and saw but also thin enough so that “complex” drilling is not required. Because simple RCA chassis parts just fit. Especially on the top layer. I had the most problems with the DACT volume control on the front. But 1 minute with the chisel and voila.
