I have an Emotiva TA1, Class A/B 60 watts per channel at 8 Ohms, and at times the LGK 2.0's are clipping when playing loud.

Thinking about connecting a Schiit Vidar 2 or Aegir to the Emotiva TA1 preamp output.   

The Schiit Vidar 2 is a class A/B amp (8 Ohms 100 watts per channel) and the Aegir is a class A amp   at 8Ohms 20 watts per channel. 

Not sure for LGK 2.0's or Encore XLS speakers which of those two Schiit amps are the best fit?

Thank you for any information or advice.

If the LGKs are 83 dB sensitive, then you need lots of power.

The Aegir is an amazing sounding amp, but it will not get the LGKs loud at all. I have an Aegir with Polk R200s (86 dB sensitive) on my desk, and at 100% full volume on my preamp, the Polk are barely too loud on my desk. If I replace the Polks with my Tekton Mini Lore Monitors (95 dB), now I can get the Aegir to loud levels. But those Tektons are too big for a desk.

I would not consider a single Aegir for anything under 90 dB sensitive.

The new Schiit Tyr looks pretty tasty, albeit at a considerably higher cost for the two monos.

If you're going to play the LGK 2.0s loud, you really need to put an high-pass filter on them around the 80-120 Hz range, and cross them over to a subwoofer. That will take all of the bottom end off the LGKs, giving them a lot more headroom to play louder in the mids.

When I play them on my main system in my living room, I roll them off at 120Hz, so I can push them a lot harder than if I let them play full range, as I normally do on my desk, which I rarely push to even 1W since it's mostly podcasts & YouTube with occasional music.

If you swap to monoblocks or even a separate stereo amplifier it's pretty easy to install a high-pass filter between them and use a subwoofer.

And if you're looking to really push speakers to 95+dB I would look at the X-LS Encore, as they'll handle a lot more power, providing a lot more bass extension to 55Hz as well, without the need for a high-pass filter.

The Emotiva has a 90Hz low pass and filter that I can use for the subwoofer.  I was thinking about a SVS 3000 Micro.  When pairing LGK 2.0's or Encore X-LS's are there special considerations that should be made in o find a sub that pairs well with those two GR Research speakers or other GR Research speakers?

Below are the specifics on the crossover on the Emotiva TA1 Integrated Receiver:

1 pair - stereo high-pass outputs; with fixed 90 Hz Linkwitz-Riley high-pass filter.
1 - subwoofer output; with fixed 90 Hz Linkwitz-Riley low-pass filter.

[Hobbsmeerkat]

Generally speaking, a sealed subwoofer with a fully adjustable variable phase knob will give you the most flexibility for blending.
(Avoid subs with a 0°/180° phase switch)

And they will blend well with either  the LGK and the Encore without much issue, if any.

Good morning,
I have ran the Emotiva TA1 with a Schiit Vidar into the XLS and it worked well, it was a bit warm for my taste. I did change the preamp to a Freya+ because it was not as detailed as I wanted. I am not sure about Aegir, but I would probably want to run them as mono to get the extra power, but everyone that has them says they are awesome amps. I agree with Hobbs, the phase adjustment is critical. I was running dual 8” subs and trying to blend them in with the low pass filter on the TA1, I could not make it work, probably more about the quality/adjustability of the subs than the filter. With my limited experience I can recommend the Vidar with the Emotiva into XLS Encores.

Kelly,

I’m running a pair of Vidars as monoblocks to power our X-SLS towers using a Decware CSP-3 preamp and a Pine Tree Audio transformer adapter. There's just something about mono blocks that improves everything with that extra power/headroom.

Aegir is not Class A, it is Class AB with circuitry that removes the normal GM halving so acts like a Class A but delivers about 3dB more power efficiency.

My blanket recommendation for a power amplifier has been a Purifi based model. It’s class D, but insanely low distortion and noise with plenty of power for basically any speaker you’ll have in the future.

I am tending to agree with this. You can get a Purifi Eval1 from VTV for $1000 and it will compete against amps 10 times it’s price. All while not racking up your electric bill.

[HT1278]

After you mentioned the Purifi Amp I ended also looking at the Buckeye Puifi Amps.   I still have a lot to learn about this.  Thank you for the heads up.

I am considering getting a Freya S for stereo purposes and using "home theater bypass" then I will have XLR connections from the Freya.  I am not getting the Freya for a while, so another wrinkle is that my Marantz NR1403 AVR only has unbalanced preamp outputs.  Could XLR to RCA cables be used in this case or are voltage concerns an issue that would prevent one from using XLR cables from an AVR to one of these amps like a Purifi based Class D amp?

Going from rca to xlr is not a problem at all  I do it on several preamps I have that are single ended. You will need either an Xlr to rca adaptor or a cable. I prefer cables. This is the one I use which are really good.

Do you work for them? 

I guess your policy is that no one should offer up any opinions or businesses offering good sounding products?

Ok, allow me to edit my statement.

The VTV Purifi Eval1 is the greatest amp ever made and it requires no electricity to operate.

Is that better?

[opnly bafld]

 
Sorry forgot this is in the GR Research circle (please delete my posts Hobbsmeerkat).

[mkrawcz]

My statement is based on the fact that I have and go through a lot of equipment both diy and consumer. I have had a lot of high end stuff in the past, and I stand by my statement that the Purifi class d amps compete with $10k plus amps. They are not like the rest of the class d amps. No they are not end game, but for $1k, good luck finding something better with that kind of power. Fortunately, these companies have trial periods so you can check it out yourself and compare it to what you have already. I singled out VTV because they offer an assembled Eval1 specifically which I personally own.
