small footprint Class A mono blocks and pre amplifier


Would appreciate the forum's assistance regarding small footprint solid state Class A mono blocks and pre amplifier. My entertainment center is only 18 inches deep. Height and Width no problem. Depth particularly with cords is a problem. Current system consists of Crites Cornscalla  speakers, Pass Labs Int30A, Pass Labs XP15,Clear Audio Turntable, Tracer tonearm, Hana MC cartridge and Lumin D2. Speakers very efficient. Prefer to buy used. Budget about $8,000 for mono blocks and pre amplifier.

Bakoon AMP-13R of South Korea / Japan. Approximately USD $6K for this integrated (SE inputs). Class A/B (I think, but not sure). 

+1 on @charles1dad 's Valvet recommendation. 
McCormack Micro Power Drive and Line Drive.
Though the amp is probably A/B/

Thanks to everyone for your replies.  Rugyboogie, Ive been searching the ads for Pass Labs XA60.5 to no avail. Wasn't aware of the Aelph, Zero and will look into them. Charles1dad German Valvet look really nice if I can find a pair used within budget.Mijostyn can't put behind speakers. Got 2 feet on each side and above each unit. Just don't have the depth. Looking for older Pass Labs in good condition as you and Rugyboogie suggest. Plan to run fully balanced system. What Pass Labs preamp would complement the Aelph, Zero?
