Default need sound attenuator

there is two setup

1st : PC (linux mpd)-> DAC-> Amp ->Speakers....this system sound amazing but sound is too loud...

2nd : PC (linux mpd)-> DAC-> Classe ssp-300 7.1 analogue bypass ->Amp ->Speakers

the 2nd way it makes my sound dull ...unlively in plain language cant live with the second option...

first option is too loud...unless not HARWARE controlled the voice is of the charts...

i need a sound attenuator which will just control the sound without distorting any idea where i can look these.....also i dont have any soldering skilss so lesser the DIY the better for me...

The advice from AndrewT is spot on, but still it might be an idea to tell us some more details.

Which DAC are you using?
How is the DAC connected to your linux box?
Is your linux box upsampling to 48Khz before sending the signal to the DAC? If it is then make it stop doing that, it will use a cheap and nasty resampling algorithm.
Which amp do you have?

DCX has 6 output channels.
Rotel has 6 channels.
The rotel is your attenuator and your amplifier for all six channels.

You cannot and should not insert any other attenuator anywhere in the system.

If you remove the rotel, you will need a 6 channel attenuator and 6 amplifiers.

It looks like you are confirming that the rotel 6 or 8 channel amplifier has no attenuation built in.
In that case you need a 6 channel attenuator between the DCX and the Power Amplifier.

No. Input to DCX should never be attenuated.
