"now i need to get amplification that will be most suitable for them"
It would be helpful to know what aspects of sound reproduction are most important to you as "suitable" means very different things to different people. But, without that info, I would think it would be hard to go wrong with something like the Hegel H80 as it's a good all-rounder and has the onboard DAC you're looking for. There's also a nice H70 for sale here now for $900 that would probably get you close for less than half the price and leaves room in your budget for decent cables/interconnects. I found the Acoustic Zen Silver Reference II interconnects (Silver Ref I would work too, that is if you even need interconnects) and Satori cables (you'd need to buy both used, which is the way to go anyway) to be a nice match with the Venere 2.5s. They let the detail of the tweeter come through without being at all harsh and fully communicated very real and palpable mids the speakers are capable of. I'll have to defer to others on USB cable recommendations. There are undoubtedly other (and maybe cheaper) cables that would work well too, but just wanted to throw out one recommendation from experience. You could try some cables from direct sellers (Grover Huffman, Morrow, etc.) who usually have generous trial periods and return policies so you can try at home, and they offer good value. Hope this helps and best of luck.
