Best budget preamp for my entry level system?


Greetings everyone. I need some input on the selection of a pre-amplifier.

After years of making the most of and enjoying my existing budget system, I'm kicking in a few dollars to upgrade my system. I'm currently using a Marantz 2215B receiver, a Pioneer PL-550 turntable, a pair of Boston Acoustic CR-9's, an old junky JBL sub, and a bluetooth adapter to connect to my i-phone for streaming audio....

So far I have purchased the following replacement / upgrade components: Zu Audio Omen Dirty Weekend Speakers, and a Emotiva UPA-200 Amplifier.

>>> Any recommendations on a pre-amplifier? I'm definitely thinking pre-owned, and something around $300. Would want to connect my existing turntable, and a good quality CD player to it in the future. Also like to use my I-phone as a source as well through either a bluetooth adapter, or plugging in directly. I mostly listen to classic rock and rock.

Thank you, any feedback provided would be greatly appreciated!

I read the review on the USP-1, sounds like a lot of bang for the buck. The most up to date Emotiva equivalent is the PT-100 for $329, and includes a DAC, phono input, etc.

If you hadn't already purchased the amp, I would have suggested an integrated. Since you have the amp, and wish not to sell it, the PT-100 offers allot for the money; phonostage, DAC, headphone amp, and 3 additional line level inputs. 
For well under $300 you can get a B&K Reference 20 or even a Reference 30 preamp and, although not 2 channel, they perform exceptionally well in 2 channel. These originally sold for around $2500 and have a lot to offer. I own one of each along with a lot of other stuff and I am amazed at how they clear and detailed they are. 

To play vinyl you will need a phono pre. A Schiit Mani for $129 would serve perfectly.
the newer preamp has built in DAC, and related inputs. Nice, saves money, need for more cables both signal and power, and saves space:

 Unless you get the 'I need a better DAC bug', in which case, I would be happier with the matching style of the older Pre-amp.
Well, the USP-1 is ~10 years old. The PT-100 is new. Not knowing the comparative build quality or sonics hard to say which way to go. Likely the new one could be returned if it doesn't work out. Both seem to offer much at their price point.

Matching style is a consideration. Only the OP knows to what degree.
