Merrak Monoblocks without pre amp

#1

Just picked up a pair of Meraks at a good price to feed my Vega and Aries Femto. Am I ok with this setup? I don’t need a pre amp right?

37 people read this and no one wants to answer my question?

#3

I don’t have a Vega, but, if it’s got a volume control, you are good to go.

Thank you. I will be receiving the amps on Wednesday. I am under the impression that it will work but the pre amp may offer better EQ. As long as it works I will be happy.

#5

I ran my DAC direct to amp for a couple of years, sounded great. Added BHK pre, sounds appreciably better!

Ok understandable. Separates always have been pre amp and amp. I can enjoy this until I get more funds. This will be my first mono blocks so I am happy.

#7

I’m sure you will be very happy, until your audiophile symptoms flare up again. LOL. Enjoy!

Thank you, my wife keeps me in check with those symptoms.

I would look for a second hand Auralic Taurus. Great sound!

It depends on what speakers you will use, the sensitivity is critical.

Hi Xuanqian,

Let me tell you now…I have B&W XT4. sensitivity 86dB spl (2.83V, 1m). recommended amp power 50W-150W into 8 ohms.

#13

86dB is relatively low, suggest with an analog pre-amplifier if possible but should be good without it as well.

Ok I just received them today and they are not sounding so hot. I know I have to let them warm up more. I am at 40-50 on the volume for the Vega and my wife thinks that is loud so I am stuck at around 35. I don’t think that would be optimal. Does the pre amp allow me to go to 100 on the Vega? I am using a cheaper pair of XLR which I am replacing for the Audioquest Elements Water. It does sound better at higher volume. Just as long as I am not doing harm to my system at lower volume I will have to wait for the preamp.

#16

Sounds normal to me. If they are brand new amps, they may take a while to break in. the fact they get loud at 40-50 suggests you’ll have the proper headroom for dynamic sound.

#17

I thought the Vega should be set to 100 for best SQ? Since, I can not do that I guess this is where the pre amp comes in to allow this?

#18

Yes, you need another attenuator (preamp) to do that.

#19

Roon can attenuate the signal going to the streamer is that a good thing?

#20

Generally when it’s done in a digital way, it’s not a good thing …

ok good point. I will keep the volume as high as my wife will allow. lol

One solution would be a passive preamp or even a quality attenuator - no amplification. Schiit makes a decent one for $49: https://www.schiit.com/products/sys. Of course, you can go as high as you want. A good stepped attenuator by itself (no connections or case) is $250+.

This allows you to keep the VEGA gain higher by turning it down at the attenuator.
