Musical Fidelity V90-AMP Noise Issue
Hi Erik, Thanks for the reply. I purchased it from Music Direct back in March. It was a demo discounted item, but I believe it still came with the standard Musical Fidelity warranty. The sound has been happening since I have received it back in April. I guess I was wrong to describe it as a hiss. More of a jittering buzz is would be accurate. Sounds like it is worth sending message to MF to see if they have any solutions. Cheers, Matthew |
If it's a hum or buzz, it could be DC on the line. You would need something like this to filter the DC http://emotiva.com/products/accessories/cmx-2 Has this been the case since the unit was new or did it just start happening? Have you changed anything electrically (i.e. new appliances, new outlets, move equipment, etc.)? FWIW I have a Musical Fidelity M6si and there is no internal noise of any kind emanating from it. |
Understood. Assuming you're in the U.S., other than Randy Bingham there is no email contact. Please let me know if you have an address for the UK. You may want to talk to the place you purchased the unit from. Back to electrical, if it is a DC issue you cannot resolve that simply by trying different power receptacles. You would need a DC filter. |
Hi Matthew, I have the same issue with my new v90 amp that I received from Music Direct yesterday. The unit is a new one, and I noticed it immediately after I turned it on. Did you hear back from Musical Fidelity? Also the volume doesn't go down to zero, so I can't turn it down to a very quiet volume level. Is your unit like that also? Regards, Jay |
Hi Jay, Never received a response from Musical Fidelity's USA rep. I did reach out to Music Direct and they were very responsive at first. Even though I was out of my return window they attempted to contact Musical Fidelity on their end. However, I never received a response from MD and MF after that initial point of communication. I also had the same problem with the volume not going to zero. Sonically I thought the V90-Amp was really nice for the price. I was happy with the DAC, and it drove my vintage Polk Monitor 4s very well. In the end I was getting sick of hearing it make noises on my computer desk and recently traded in the V90-Amp to a local HiFi shop for a NAD D 3020. |
Hi Matthew, I'll contact Music Direct and Musical Fidelity and see what they have to say. That's too bad you didn't receive a response from either company. If both issues are normal, I'll likely keep it as it does sound quite good, especially for the asking price of $149 for brand new units, as they are now discontinued and on clearance. I hope your NAD D 3020 sounds terrific and even better than the V90 Amp it replaced. Cheers! |
