Hoping for advice on a possible purchase -- Yamaha turntable, EAR preamp, and Cary amp

[samuelmarius]

Greetings, good people of Audiokarma. I'm hoping some of you might not mind sharing your wisdom, warnings, thoughts, knowledge, and opinions.

I'm thinking of buying the following from a guy:

• Yamaha YP-D8 with Stanton 881s
  
• EAR 834p Preamp
  
• Sound Masters Line Buffer Preamp No. 9 Ver. 2
  
• Cary CAD-308-SA Hybrid Amp

For everything he wants $3,600 USD.

This would be my first major investment in a turntable system, and my first foray into tubes.

I have an AR-XA, paired with Yamaha rx-597 and b&w 620m's -- and love them. I also enjoy my partner's JVC turntable, which is paired with a Marantz 2010 and HTD bookshelf speakers. I recently ordered a Sansui 8080DB ($300) as well, though I may cancel that order.

I'm happy with what I have l, so I don't need this equipment, but the deal seems good and the equipment seems hard to find/high quality, so I'm tempted (though my partner is horrified).

Mostly I listen to blues, classical, jazz, and electronic.

I'd be grateful for any advice, perspective, knowledge, opinions, or anything else anybody wants to share. Is this a good deal? Any other thoughts/ideas, or anything else I should think about/consider? Thanks in advance! Cheers!
