I'd rather have one great setup between analog and digital rather than two mediocre setups. So, if I were you, I'd upgrade the digital or wait and save for top flight vinyl setup. Both mijostyn and ghdprentice make good points.
My vinyl setup is more costly than what your budgeting for and rarely gets played since my digital outperforms it. Continuing to go with two setups has been costly for me, getting two setups to be competitive with each other has resulted in far greater expenditure vs. what I would have spent with only one top flight system. I'm now in position that $10k phono stage and at least $2k cartridge will be required to compete with digital, cha ching, cash register keeps on adding up. I'd likely give up vinyl if I didn't have 3k+ albums.
