At 1,000 bucks it is difficult to buy good system ...But possible...
I am happy with powered Edifier speakers but if i had money i will buy better one for sure...( My Sansui alpha can drive anything but for now i dont want to invest 1000 bucks on passive speakers alone i am happy with which i could achieve as secondary system (speakers) versus my main one (K340) )
How much cost a linear power supply ? I own a Chinese one very good at peanut cost... I am happy with it if it goes on for few years as now... (No power button on/off i disconnect it at night but it is a better than a IFI linear supply i paid almost 3 times the price)
How much cost a good purifier ? I bought a Chinese one which work better than my Panamax for peanuts...
How much cost a pre-amplifier equalizer ? I bought a Douk T8 for peanuts
How much cost an acceptable dac ? I bought one from Douk the Q11 ... Peanuts costs...
Now , the main important part, any speakers even in nearfield listening need acoustic corner control... ( i use Helmholtz resonators i make with different size tubes and tune, others acoustics controls could be needed relatively to your room parameters)
All this will be not satisfying without clean power and a purifier is not enough, i make my own grounding boxes for all pieces of gear even the purifier and the linear power supply...
I hope i suggested to you some research clues...
Acoustics controls matter at any speakers price, grounding method matter at all price...
Others things matter but i dont want to write a long post...
For the same price i also own my main system which is headphone (AKG K340) Sansui alpha amp and Hidiz pro 80 dac...
because i bought all this some years ago the total price of my 2 system do not exceed 1000 bucks by much...
If i dont count all the minerals i used in my grounding boxes and my other homemade tweaks...
To create a peanuts cost acceptable system ask for much time and experiments...
Purchasing any system at any price is not being an audiophile but being a consumer we must study and experiment...
Read about acoustics concepts.... And grounding boxes homemade design...
Others will advise you to spend more money...
It will be an error...
Study first and learn how to make the best with a 1000 bucks system... Replace the speakers you own if you are not happy by low cost one but better one... Upgrading without studying and thinking is not good idea...
