Separate Phono Pre - $$ before I will hear a SIGNIFICANT difference vs. integrated?


In my search for a new Pre-Amp - one of the factors that I am considering is the "Line-Stage" vs. "Built-In Phono Stage" factor.

If I opt for a Line-Stage type - I will probably want to add a separate Phono Pre. I presently do like to spin some vinyl, but I only do it occasionally at the moment because I do not have a permanent place to place the TT. (I store it carefully when not in use)

TT = AR "The Turntable" with Straight (Jelco) Tonearm and Shure MX-V VMR Cart

Q1. How likely is it that something affordable (Like Schiit Mani around $130 USD or Mofi Studio?) will sound equal to or better than the phono stage of the NAD 7220PE Receiver that I am presently using?

Q2. How far up does one need to go in order to note a SIGNIFICANT step-up in Audio Performance?
(Maybe something with Balanced Outputs that is easy to locate CLOSE to the TT?)

Many options for a phono pre. Don't rule out the used market. I got a Graham Slee phono amp to use with my NAD integrated. But, the big difference is that I also got the Slee power supply. The power supply is important as one previous poster stated.

Anyway, you have plenty of options.
I'm pleased with my musical fidelity lx lps. Bought for only 199 on sale from 500 bucks closeout....best 199 I ever spent.
