Just to share my experience since I have both Maverick tube audio DAC and Rotel RC-1070. I did a test, to me, witht he preamp sounds better than without. Also, I tried with and without the DAC, I couldn't hear any difference. So, I would suggest to get a preamp. And before I got the RC-1070, I got a Adcom GFP-710 for $200. It sounds good, but it sometimes sound harsh. The Rotel sounds darker, not as harsh, and can listen for longer hours without fatigue. Although I sold it and get a audible illusion tube preamp, I actually think RC-1070 is quite a good for the money. You can find one for $300, $100 over your budget though.
