  • To put some perspective on it, a failure of a solid state amplifier is very unlikely.

    The most likely thing to go would be the power supply capacitors, but with regular use it’s even less likely (regular charge keeps them fresh!) and the symptom of failure there is buzz, which gives you a good warning.

    Transistors and other things could fail, but then the most likely case is a small pop and then a non-working amp, it’s unlikely to fail dangerously.

    They’re fairly safe overall, especially if it’s been running well for 30 years I would expect it to do so for 30 more at least.






  • I don’t think this is really a concern.

    When digital was first introduced, it was mainly used as a recording and mastering tool, and lauded for the improved quality it could achieve.

    The Telarc record of the Cleveland Symphonic Winds was one of the first with digital recording, mastered to vinyl. It used the latest tech at the time, a 50kHz 16 bit recorder controlled by a DEC PDP-10. Full story here, it’s fascinating.

    Anyway that is to say, I would separate out the recording and mastering technology from the delivery format. Yes, there is something special about an AAA record (analog recorded, mastered, and delivered) as opposed to a DDA or ADA, but the latter two can be very good.

    Remember also that in the studio they have the best DACs and ADCs money can buy, and excellent equipment to review and quality check each step of the process. So when you get a vinyl record mastered digitally, it’s mastered using like a $5,000 DAC. Unless you also have a $5,000 DAC, you won’t get quite the same experience (debatable of course, but I’m not up for that debate today thx).

    So there is value in it, even if the steps leading up to cutting the groove are part or all digital.



  • Yeah, disagree there. If the album is cut wrong with too narrow of a groove pitch then it could be a problem, but then it’s a mastering mistake by someone without vinyl mastering experience, not a problem with the format.

    But most of the problem there is handled by the RIAA curve, which means that the amplitudes on the record are lessened in the lower frequencies, and amplified more by an RIAA preamp. Means the needle isn’t traveling as much as you’d expect even for I.e. 10Hz lows.

    Try the Holst suite by the Cleveland Symphonic Winds, Telarc record. First movement, the Chaconne, the bass drum hits at the end. Fantastic realistic whole bass boom, way more depth than you’d expect and you’ll be left wondering how your needle didn’t jump the groove. It doesn’t sound better than digital per se, but vinyl is fully capable of it.
