A question of turntables, amps and phono pre-amps.
Against my strongest advice son and his mum purchased a turntable for
christmas but couldn't use it as his amps didn't have phono input so today we popped into Richer Sounds and picked up a phono pre-amp. Wired it up and he un-joyed the whole reason CD's became just so popular... (E.L.O. no sparkle or brightness,dull and lifeless, just as I remembered Vinyl to be) Anyway... he listened to it for about an hour, switched it off then came back to listen again but his amp appeared to be non-amplifying so he plugged the TT/Pre-amp into another amp (the one that electrocuted me previously but still passed PAT test) and that too didn't respond to any audio source but if it was turned up to 99 with a regular audio source there is the faint sound from the speakers then the amp shuts down. Is it possible the phono pre-amp has trashed 2 amplifiers? When it was set up first there wasn't any problem or signs of impending doom. Tried a 3'rd amp (radio source not TT) on the speakers and speakers work fine. It's got me baffled. Optical, bluetooth and analogue inputs are all non-responsive. Do we have an amp. killer? TIA Pete |

But if your vinyl really does sound like you say, you've got something very wrong somewhere. A reasonable cartridge and pre-amp won't be lacking in brightness, compared to CD through the same system. The differences are rather more subtle than that. -- *Real men don't waste their hormones growing hair Dave Plowman London SW To e-mail, change noise into sound. |

From the sound of it yes. However it must have a very advanced
disintegration device to do this sort of thing. The normal issue is that the software controlled input switching gets scrambled so you cannot make it work but from what you say it sounds worse. Hard to see how a preamp can do this. As for how it sounded, well like most things you get what you pay for and many turntables sold with cartridges are let down by that cartridge.

No not really, maybe it has some form of protection against dc on its
analogue inputs. I had a Marantz like this and as it claimed to be dc coupled I fancy this was the main reason it had it, nobody wants to put huge amounts of DC into a speaker.

Hmmmm We scraped around the cable boxes and found some pretty old, skinny leads, the type you'd get with a cheap CD player back in the day... So perhaps low grade interconnects between TT and pre-amp and pre-amp and amp might actually be making a difference... Will get some slightly better ones and see.. |

Brian Thanks Brian, It comes with an Ortofon OM 5E cartridge which from my quick research is somewhat lacking.... but it's better for the boy that has no idea about handling records and the fragility of such components to "practice" with a cheap one rather than accidentally skip an expensive replacement across the turntable mat. |
