small footprint Class A mono blocks and pre amplifier

br3098. I am enjoying immensely my Passlabs Aelph Zero Class A mono blocks. They image flawlessly with my Passlabs XP30 line stage preamp.  They get very warm but not so hot that I can't put my hand on top for short period. I do have plenty of space on 4 sides and we have ceiling fans that keep the air moving in a large room with 14 foot ceiling. I appreciate Noble100's concern the heat is below combustion temperatures.

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?

Thank you forum members.  I purchased a pair of  Pass Labs Aleph O monoblocks. Would appreciate any advice on a older Pass Labs preamplifier. Atmosphere appreciate your concern on the heat but I will make it work. jl35 looked at the Capri but I have a Pass Labs Phono and Lumin D2.

Nobel100/Tim. You are exactly correct.  I often times exhibit poor judgement and impatience. If the Pass Labs Aleph O monoblocks. dont work out I'll put them on Audigon for sale and try something else.  Maybe Class D.  Thanks for your advice
