    Any opinions on the "warp filter" that comes with ifi phono stages?

    Ifi-audio include a "warp filter" in their preamps- essentially it acts to filter out the low frequency L-R content of an LP in order to reduce the impact of warps. This works because low frequency information in LPs is passed through an "elliptic filter" that causes the L and R bass content to...

    Sansui QRX-5500 Died changing the lamps

    Good Evening AK'ers. So I did a rather stupid thing tonight. I had my 5500 apart on the bench for a cleaning and lamp replacement. I'm a novice at this so bear with me. I changed out the fuse lamps and those were all working great. I needed to replace one selector bulb and I forgot to turn off...

    Amplifier Recommendations for Harbeth Super HL5+

    Hi folks, I've recently picked up a pair of Harbeth SHL5+ and I'm in need of a new power source for them. Doing some research, it seems most owners are recommending Luxman, Accuphase and Rogue Audio. I was wondering what the consensus is here. I was also looking into vintage tubes but I have...

    Integrated Amp for Monitor Audio Silver 100

    Hi, any good suggestions on a best value integrated amplifier for Monitor Audio Silver 100 at three price range (i.e. <&1000, $1500 & <$2000)? I'm believe Monitor Audio Silver 100 is leaning to a bright to neutral sound signature and hoping to balance it with a more musical amplifier (leaning...

    Hey, I recently picked up an Aiwa 3090 Cassiever from Goodwill, and besides all rubber bands on the tape deck having deteriorated, it worked and sounded pretty good. However, I switched on the loudness trigger, and it knocked my right speaker out of alignment. :'(. I am looking for advice on...

    Tape railroading

    I got a set of pre-recorded cassettes, wound with BASF chrome tape. I put one in my deck — a 40-year old Panasonic/Technics — and was horrified when I heard the sound of tape being chewed and the sound all distorted. I pulled it out, and it was railroaded! Then I recalled that since I got this...

    Sansui 4000, Distortion on Both Phono Channels

    Hey everyone, I’m brand new to the vintage world, and I picked up a Sansui 4000 receiver yesterday and have come to find that there’s some pretty nasty distortion in both the phono channels. The signal seems much louder than it ought to be. Additionally, I can hear signal from Phono 1 while the...
