Speakers for Devialet

Thx akg.
1. I am using Avanti III. They are about 10 years (was earlier driving them with Bryston).
2. I am using Audio-aero Prima CD player. Have also attached my macbook through which I play my music on iTunes (high quality on hard disk). Sometimes use Spotify premium where music quality really drops. Looking at buying Aurender X100 as the media player.
3. Need to change cables as well and wondering what to upgrade to.

many thanks for your prompt assistance - I am new to this forum.

Thanks akg and leeagc. I had recently upgraded from Devialet 200 to the 440. The built in streaming function has still not been delivered in Singapore and is expected in Q3. I have a dedicated 20 amp power supply. Heard Kharma Excquisite LE and was blown away. The dealer was recommending DB7 as a good match. I had earlier looked at Raidho D2.1 as well as Focal Sopra No 2 and SF Amati. Very confused about the speakers but guess will work at source first and check my power cable (am traveling currently) and look at Roon. Was thinking of buying Aurender X 100 to attach to my devialet as the media player. Will that work with Roon? Many thanks for your kind assistance

Looking at around $20-25k. Have looked at Raidho D2.1 (demo piece) though still pricey. Have been recommended Kharma DB7 (impressed with Kharma Galileo but that is again very very pricey) and SF Amati.

Primary source is CD + high resolution music on hard disk. Spotify is occasional on the main deck but primarily used on Devialet Phantoms. I guess need to spend more time on the source - will upgrade to Aurender X100 as first stage and check on my power supply...Thx

Thx all. Just changed my power distributor to PS8 (Shunyata) and speaker cables to Ansuz Speakz - huge improvement in sound quality, am loving it. Am now auditioning Raidhos on Saturday. Revel Salon 2s are awesome as 2 of my friends have it but not easily available in Singapore. 
@Skanda, what would be a reasonable Price for Raidho D2.1 (demo piece). Many thanks
