Integrated vs. Separates on a Budget

You have been given much good advice. You can use the Bluesound internal DAC into your Denon. Possibly upgrade to a stand alone DAC later. The Mani is a good one purchased direct from Schiit with 15 day return, $129. Based on forum threads an upgrade to the power supply makes a significant improvement.  I have a Music Hall phonostage I could loan you for a month or so to try out the TT. PM me. 

I used to have a Nad amp from the late 80s. When it broke I changed to a Rega Brio which was a bit better. Still with my old speakers. I planned to upgrade my speakers but started to think about moving and did not know which speakers that would work. Then I found a great deal on a used Schiit Ragnarok 2 integrated and bought it. It was the best upgrade I have made! The sound improved a lot even with the old speakers. So you can get better sound by changing the amp, even with old speakers.

I do recommend the Ragnarok. You probably want the fully loaded version since it has both dac and riaa built-in. Just get a Raspberry Pi or another streamer and you’re covered.

[Edit]

The price is around $2k.

Luxman integrated or a flagship yamaha marantz in the sales... Luxman phono input also rivals most 500-700 phono stages so there is saving to be made with a good but simple integrated. 

How many watts per channel do your speakers need?  If your speakers are 90db or greater, check out a Lejonklou Boazu........

Good luck.
