    Minidisc! Huah! What is it good for?

    The editing options were superb. Moving tracks around, fade in and fade out, changing the recorded level of any track, the way tracks could be labelled and indexed etc. I use a Sony MDR for time shifting radio broadcasts using a direct digital input from a Pure DAB radio.

    Fuses - Sensetive Akai AA-1020 Receiver?

    It should say on the PCB or on a label next to each fuse and it will certainly say on the original fuses (and replacements) what they are. AT, AS and T are time delay (slow blow) while F are fast. So it might say T1.6A or F1.6A for example. Speaker fuses normally are fast blow (if thats what...

    Broken Cambridge Audio

    This reply probably isn't much help as such but on reading this I felt I had to chip in :) Transformers rarely fail (make that very very very rarely) and those that do usually have good reason due to overheating caused by failed components within the amplifier. Alarm bells ring at the...

    Pre Amp?

    You may make some gains sonically but also the run the risk of having an extra "add on" component and possible noise/ground/cable effects making their presence felt. It's quite an old amp... not that there's anything wrong with that... and out of curiosity I looked at the phono stage circuitry...

    Little/no sound from the left channel of my amp.

    We need a bit more to go on than that. Make/model ? Have you tried swapping the speakers over ? Is the problem on all inputs or just one input ?

    Hiss from my Amplifier

    Hiss (white noise) should be minimal and pretty much inaudible from any amp at more than a foot or so from the speakers. Whatever hiss an amp produces should also be equal on each channel so something is amiss. Turn the volume on minimum and start with JUST the amp and speakers and NO other...

    is my old technics su-x301 dying?

    Could be any number of things. If singing and voices are "dissappearing"but the music remains then that could be some form of cancellation occuring and may be nothing more than a dirty balance control wiper or switches etc that need cleaning. It needs a few basic checks and tests. Ultimately its...

    Can anyone recommend a system for classical music?

    The Marantz Pearl Lite SA-CD player and matching amp come in at around £1200 for the pair if bought together and are (imo) something of a bargain. I can't recommend the SA-CD player highly enough. Stunning audio quality and with the flexibilty of front and rear USB ports. I've not auditioned the...

    Turntable playing to fast

    It could be one of several things generally. I'm assuming it uses a small DC motor with either a built in or "separate" speed regulator. Separate as in separate from the motor. Unfortunately this forum isn't really the ideal place for this kind of issue. To diagnose would involve at least some...

    Marantz KI Pearl Lites seem great value?

    Absolutely. The KI Pearl Lite is a superb player in all repsects. Don't think of it as just an SA-CD player, its much more than that.

    Question about ground loops

    Is it physical ? Are the units in close proximity to each other (one sat on another). If so try moving them apart.

    Marantz PM6004 problem running my speakers

    Speakers in series is a no no for quality as they interact electrically. I don't know what it would be like in practice but the Marantz Pearl Lite squeaks in at £20 over the 600 mark and is reputed to be a sonic bargain. I have the Pearl Lite SACD and its stunning in every way. You see, with...

    Marantz PM6004 problem running my speakers

    As others correctly say, this is an impedance issue. However it goes deeper than that because impedance isn't a constant figure but one that varies according to the frequency of the applied signal. A nominal four ohm speaker may well have a minimum impedance lower than the stated nominal figure...

    Amplifier output stages

    Digital (SPDIF) outputs are often transformer fed via a special HF "pulse" transformer to give a balanced isolated feed. For that application its a perfect solution. For solid state audio there is just no reason to use them... at least not in engineering terms... but someone somewhere will...
