    Vintage Sennheiser HD 414 behaving weird

    I got myself a pair of Sennheiser HD 424 some years ago. With aftermarket strange blue hard foams (see photo) which I replaced with NOS yellow ear pads. Lovely headphones to use while at work, etc. Fast forward to last week. Visited the local thrift store and found a pair of Sennheiser HD...

    4 ohm bookshelf speakers you have loved?

    Hello Karmic Seekers, I'm hoping to make a list of all 4-ohm bookshelf speakers that the forum members have loved. Vintage and modern; economical and pricey....

    Stupid DC resistance question

    While chasing a problem with a receiver, I decided to check resistance of my speakers and speaker wires. What I got was this: Realistic T-120: a) 4.2 ohms b) 4.3 ohms Infinity SM120: a) 3.5 ohms b) 3.6 ohms These are all three way speakers rated at 8 ohms, and I just put the meter across...

    Marantz 2270 on a 3.5 ohm load

    What does anyone think? Safe to run 2 sets of speakers (8 ohm and 4-6 ohm) on a recapped 2270? Results in a 2.6 - 3.4 ohm load.... Would be only at very moderate volume for shortish periods... Safe or not?

    Connecting speaker switch to sub?

    I have a vintage amp (Nikko TRM 750) currently connected via the A speaker outputs to a Polk PSW10 subwoofer, and the sub is connected to a pair of Dayton Audio B652 Air speakers suspended from the wall. It is a great everyday set-up that does not take up a lot of space in our living room and is...

    General Question about Elekit TU-879s

    Alright guys, I've never really dealt with tube amplifiers in the speaker world and I'm just generally confused about why they seem to be sought after in some circles when they don't seem to ever have as much output power as even entry level receives and solid state integrated amplifiers. I...

    Specs on Ruark Acoustics Paladins

    Hello, last month I picked up a pair of Ruark Paladins at a yard sale for $60. I love them, but I can't find any specs online. I'm curious as to their impedance rating.

    speaker matching for pioneer a-66x.

    Hi everybody, I,m looking for some help and advice with an amp I've just bought for my workshop. After a little trouble finding the right type of amp (and buying one wrong one already...) I've gone for a Pioneer A-66x, an "ok" late 80's amp which I suspect will be good enough quality and...
