I use Marantz Professional cd recorder CDR400 w/built in mic.
Bass leaves after amp warms up?
I don't understand-after my Musical Fidelity M6i amp warms up for about an hour I notice the deep bass & kick drum aren't the same.
They sound less musical with loss of weight/depth.The notes are there but the moving of air have left.Sound is has much less impact and boreing.
I had the same problem with Bryston amp so there is no defect with amps nor with the rest of my equipment/
PSB Synchrony one speakers,AQ cables,Bryston CD Player.
My question has anyone heard similar & is there a plausable reason?

I petitioned my dealer to lend me a dedicated 250 w amp from Musical Fidelity. Do you feel this will resolve the problem?Could be, but I'm by no means certain. I would expect it to be more capable of handling low impedances than the integrated amps you've used, but once again it unfortunately does not appear to have a 4 ohm power rating. I use Marantz Professional cd recorder CDR400 w/built in mic.Couldn't find any info on a Marantz CDR400, but I did find this on the CDR420. If it is the same as or similar to that model, it does provide both AGC (referred to in the writeup as ALC) and peak limiting. To obtain recordings that are as meaningful as possible for present purposes, both of those functions should be switched off, and the recording level set such that the maximum level that is reached during the track at any time (whether or not the problem is present) is several db (perhaps 6 db or so) below the 0 db reference point. All settings should then be left exactly the same for both recordings. Regards, -- Al |
I admire all you kind people you have tried to help a brother out. Also, who doesn't love a good mystery. Fishing, it would be great to test your system with the MF M6PRX Power Amplifier. Once again, they give no power rating into 4 ohms; but state 260 wpc/8 ohms and claim it provides high current (around 140 amps), with a peak voltage output of 130 volts. This will drive those PSBs. I keep thinking about the impedance curve of these speakers, and I think this has played a major factor in your problem. (or inconsistent line voltage). Also, some advice...you should leave a SS amp powered-up 24/7. Those who don't always let the amp warm up one hour before any critical listening. Good Luck. |
