But these speakers is to listen other type of music!  Vocal, acoustics, few instruments... if I am not wrong.

You like modern commercial music, badly recorded. With bass. You do not need to spend a lot of money in the amplifier, DAC...

The driver:

These little drivers can be used in a number of applications from small theater speakers, small two channel systems, and desktop monitors. The are ideal for nearfield listening or small rooms where high SPL levels are not needed. The high Q design also allows it to be used in open baffle applications as a mid-bass driver. The LGK 1.0 is also capable of hitting a -3db down point of 68Hz in a ported box design...

Well okay then, can you at least tell me how you would connect a subwoofer to your setup with an amplifier without a sub out?

Now, new, only $280

You can connect the computer to the AVR with wifi or ethernet (cable). With a software player you can make a streaming to the AVR and it decodes the music with the own DAC. With bluetooth tue sound quality is worse but...

And you can easy add a subwoofer in the future.

First I would use of the room equalizer with YPAO system of Yamaha. It is not the best but its is OK.

These AVR is better option than a cheap old class D amplifier with DAC inside.

Yes, new and only $280.

If you have a source with a volume control you should check this out: https://dallas.craigslist.org/dal/ele/d/hafler-230/6559952616.html

The only issue is this is a pro version and requires 1/4 inch phono plugs on the input. Very easy to fix.

Get a used receiver for that price. You will have the luxury of adding a sub later on when finances allow. Just look at the marketplace here and elsewhere and get a reasonable one ...

My top pick would be a used NAD D 3020 integrated amp. It has a built-in DAC and sub out. Here is one for $300 on Ebay. A friend of mine has one as well as a lot of other expensive gear and rates the NAD as a best buy. It even has a remote control.

Consider a Dayton Audio DTA-120A or a Topping TP-60.  I have the older Dayton DTA-100A driving a pair of Monitor Audio S1 speakers.  The little integrated digital amp sounds great with a wide airy sound stage and deep bass.  The newer 120A has a bit more power and is rated for 4 ohm speakers.
I see they now have a blue tooth version as well.  I would not pair it with speakers that have a sensitivity below 89dB and as long as you don't turn it up to ear bleeding levels it sounds surprising great, especially when paired with a decent DAC.  It is an integrated amp but you can pair it with a preamp.  You will get 30 to 50 wpc of usable clean power.

Here is the Topping-

However, there are some great deals on 2ch receivers at accessories 4 less.  Take a look at the Integra which is the high end brand for Onkyo.

That is the advantadge if you play modern commercial music, badly recorded and low DR.

Again: better an AVR before amps with cheap and very old class D, specially the Tripath with more power.


NAD D3020 has the Hypex UCD, much better class D technology. With USB DAC and sub out like says OzarkTom.

The AVR Integra has Audyssey MultiEQ XT32, better than YPAO.

but new DTR-40.7 -> AccuEQ calibration

I would also recommend the NAD 3020. It's going to do everything you asked for and they really do sound good. Get a refurb. or a good looking used one to save a little more. Emotiva would also be a good option but I haven't heard one of those.

By  the way, you made a good choice with Danny's little speaker. He knows how to get a lot of bang for the buck.

Have fun and enjoy the music whatever it is you enjoy!

Here's another option, this Nuforce NuForce Dda120 integrated has digital and analog inputs plus a bluetooth dongle for a smartphone. I haven't heard this particular model but Nuforce is known for being an audiophile budget product. Maybe someone else has heard this.

This amp got Absolute Sound Editors Choice Award in 2016 so it must be decent. $249.00. Ebay has 5 of them right now in silver, black is another $100.00.

Like old and cheap class D:


Remember, your speakers are as 8 Ohms nominal.

The others graphs are awful too.

Other very cheap option. You need to be registered to see the pictures. I have some comments.

L20.5 by LJM Low THD Amp

http://www.diyaudio.com/forums/vendor-s-bazaar/313474-l20-5-ljm-low-thd-amp.html

http://www.diyaudio.com/forums/vendor-s-bazaar/313474-l20-5-ljm-low-thd-amp-post5422667.html

Poweramp but LJM can make a custom to you with preamp or potentiometer.

Problem: without sub output to connect a cheap sub. But you can always buy in the future a powered sub and connected "by high" the speakers. The same with the Audiosurce and others.

Sure than the new LJM poweramp sounds better.

EZ Husky,

Nothing against Maty but I think he tends to rely too much on measurements and not enough on what an amp actually sounds like. I'm pretty sure he hasn't heard the Dd120 or maybe any of the amps he's commented on in your thread.

The amp 100 is an amp I'm very familiar with. We have used them many times for whole house audio installations where each amp drives a pair of in wall or in ceiling speakers. We use them strictly for back ground music and nothing more. Probably any of the amps mentioned so far will sound more open, with more detail and clarity than what you are used to with your amp.

I don't think you can go wrong with one of these two amps and don't get caught up in measurements. Most of all enjoy your purchase. There's no reason to make it too hard. The reason I mentioned the Dd120 is it has some great features, the company has a good reputation for entry level hi end audio and the price is in your budget. Plus since it won an award it probably sounds pretty good. The NAD 3020 is an oldie but goody and it will smoke your audiosource amp, I have heard them both.

SNR at 1 watt of 54 dB is a horrible, unacceptable measurement no matter how audiophile you are.

Very good measurements do not guarantee that the sound will be very good. It can be sterile, cold ... But such terrible measurements guarantee you that it is a terrible purchase. Spoils the sound yes or yes.  Only at very high volumes it will have a better SNR. With noisy music and very bad recorded.

The max power is 39 watts at 8 Ohms. Then the SNR is about 70 dB, already unacceptable.

But of course, how important is mathematics?

What will be the next discussion? flat Earth?

However, there are some great deals on 2ch receivers at accessories 4 less.  Take a look at the Integra which is the high end brand for Onkyo.

https://www.accessories4less.com/?type=&page=category&action=&id=stereoreceivers&skip_redirect_suffix=&mode=&search_query=&category=&thumb_sort=store_price.asc

I'll second the Integra receiver recommendation. I got the Integra DTM-40.7 from Accessories4Less, it is an impressive and versatile integrated.
