Problem with system


Last yr I purchased a Schiit Bifrost.  It worked and sounded fantastic for 5 days, then I lost dynamics and clarity.  I ordered another Bifrost  thinking it must be the dac.  But no, it still lacked dynamics, clarity.  So I sent in Bryston amp, got sent a new amp.  Still lacked detail clarity.  Sent in preamp, was told nothing wrong by Bryston.  Ordered Gungnir.    Plugged pre and Gungnir into system, still no dynamics, simply lost detail, dynamics.  Sent Gungnir back for refund.  Of course I switched out speaker wires, even ordered a cheap Cambridge integrated and Dali speakers to troubleshoot.  I tried all iteration with components. Seems to be preamp (bp6).  Anyone ever heard of a componant (in this case Bifrost dac) damaging a preamp?  I’ve been trying to resolve now for a yr. Just ordered bp19.   Thanks

If a component failed somehow after five days, it would be under warranty. If the same type of component but new sounded the same as the previous one, that component isn't the problem.

Thinking there is an issue with your speakers, if everything else is checked ok. 

Bad driver, or something bad in the crossover.

To really troubleshoot, you would unplug everything, clean all cables, connectors, etc...

Plug it all back up, go down each component testing as you go. If that doesn't point you in any direction, you start to swap out components one at a time, including cables. 

+1 @mswale - swap out 1 component at a time after making sure cables+terminations are cleaned.  I suspect preamp or speaker, but also check your ears/hearing

Another maybe harder/costlier method is find a good audio chain then swap your components in one at a time to find problem component.  

Perhaps, I missed your main system transducers.  When was last time you tightened all screws and cleaned terminals?

See above, I bought new integrated and speakers to troubleshoot.  Cables were swapped out also.  Speakers were taken to local repairman.  He hooked them up to his system and then called me to come pick them up.  He said they sounded very competent.  No issues.  Aerial says crossovers on model 6 don’t blow, but check tweeter (they sound normal on integrated to me).  Checked ohms on both connectors on each speakers, across each binding post 4 ohm if I remember correctly, complete circuit.  I took a year to go through all permutations of possible problems ( that I could think of).   Whatever is left, no matter how unlikely, is the problem. 
 

Thanks everyone for your response.
