Hoping for a recommendation for stereo amp around $1500 or less ($2k max)


Powering ascend acoustics towers with RAAL ribbons and running a powered rhythmik 12" sub which is currently integrated with my onkyo tx8270 2.1 receiver crossed at 50hz.  I want to use my topping D90/A90 dac/amp stack and use it as a dac/preamp using the remote to control the volume on the dac while leaving the volume knob in place.  Will most likely run balanced out to the amp.  I need to have some way of integrating the sub with the main speakers so the amp would need to have rca full signal out so I can use the dial on the sub to adjust crossover.  If there's a better way to integrate the sub I'm open to it.  I want an amp with hopefully 200w or more and neutral clear but fun/powerful sound like my A90 does for my headphones.  I'm totally new to the world of separates and looking to let my speakers show their maximum potential.  So far I've come across outlaw audio mono blocks but they don't have rca out to go to the sub.  Also came across parasound classic which looked pretty nice but you guys probably know of something much better.  Thank you!

I'd be cautious about that VTV amp.  They claim 425 watts at 4 ohms and 1% THD, but the 20 to 20 kHz power rating at 4 ohms is only 100 watts.   
@brandini,
Moving from your existing lightweight Onkyo receiver to a dedicated amplifier for your Ascend/RAAL speakers can be a worthy step up IF you choose well. It seems your Topping D90 offers (dual-active) preamp outputs (XLR & RCA), so you could actually run one set of XLRs to your amp, and the other set of RCAs to the sub. As you may be aware, lower model Rhythmik sub amps offer only RCA inputs, upper models offer XLR, if you wanted to flip it and run XLR/balanced to the RA sub. Not sure which RA sub/amp you have.

AMP & Budget;
Class A/AB, your (4ohm) speakers deserve a good stable amp with some real (weighty) transformer(s), and capability to run lower impedance swings with ease. The Frank Van Alstine AVA SET 400, w/optional XLR comes close at your top budget. Class D Purify, such as your thought about the NAD C298 could work too in terms of power and budget, sound is up to you. I’ve been considering testing both of these in a secondary setup.

Taking your time to research and secure a really good amp will pay off.

Ask amp manufactures first about your Topping D90 Balanced/XLR output voltage at 4 volts:

"Dual output ports:"
"Topping D90 is equipped with dual output sockets, XLR outputs offer 4Vrms output power at 0dBps, and the other output port, an unbalanced RCA offers 2Vrms output power at 0dBps. It provides enough power to power any of your demanding devices, whether it’s headphones or a speaker system. The D90 can send a signal through both output ports at the same time, so you can use multiple tools at the same time. It is equipped with a volume control function, so it can be used both as a digital-to-analog converter and as a preamplifier converter. The volume control can be turned off so that the D90 works only as a digital-to-analog converter."



Thank you for the extra info.  I would be going out the back of the A90 amp since the balanced out on the D90 is already taken by the cable going to the A90.  I assume the result would be the same.
I've noticed lots of bel canto recommendations for older units.  This has me wondering if I should save a bit more for a new bel canto unit since they seem to last a long time unless I'm mistaken.  I don't mind spending a bit more for something that's going to last decades and is easily repaired. 

Would you say bel canto is a quality brand with good quality worth saving for?  I've seen some questions raised online about NAD build quality and VTV build quality but haven't heard anything bad about bel canto yet.  It seems like they're the amp equivalent of and old toyota that won't die but with the performance of a sports car.
If you use xlr cables.
this lil beast is great, and with looks to match, is a great powerhouse with plenty of headroom.  I’m seriously considering the purchase myself for a nice backup!

@soix I see that you have recommended the D-Sonic M3a-800S amp a few times on A'Gon. 

Do you have this amp? If so what is the sound characteristic? Would it be a good match for a bright speaker?
