Vintage Krell Amplifiers from the 80’s & 90’s.


Hello all! What do you think of the Krell KSA-100, the mighty Krell KRS-100 or the Krell-200 Reference Series Monoblock Amplifiers? I think it is better than the Krell KAV. The KAV is good I just think the KRS is better sounding in the middle and highs. Both have great bass slam. I have also owned the mighty FPB-700 and the Evolution 402e as well as the EVO One. Some say the Evolution 600 and 900e was better than the Evolution one. I can't comment since I haven't own them. Hard to beat a high current Pure Class A Monoblock Amplifier. What are your thoughts? Also the Chord SPM-6000 was incredible as well. Please chime in.

I listened to everything I wanted to try, years ago. I like Pass sound so I went with Threshold, I liked the sound of tubes so I went with Western Electric and Mac.

Then there was my Class A phase, 15 years with Krells KSA 100 and 250 both all hot rodded.. I’m not kidding my MC240 Macs ran cooler in the summer than either Krell. MAN they could spin an electric meter when I cranked them up or not they still sucked the pole dry 70s, 80s and 90s. I loved them..

I ran Strathearn ribbons with those they dipped to 2.0 ohm load... NEVER a problem. One of the best combos I’ve EVER heard. CJ pre amp.. Good phono stage back then..

Fully refurbished Krell KSA-250, probably the best sounding power amp I have ever owned. The first time I used it, even my wife and children were impressed by the upgraded SQ. Sold it about 10 years ago and regreted it ever since.

I own older Soundlabs that are TOUGH to drive. When I bought them I had a pair of pricey Lamm hybrid monoblocks. A friend was about to buy Soundlabs because he loved mine, so he trotted over one day with a KSA250 that he could purchase to drive them. Well, after about two minutes after putting in the KSA250, all jaws in the room dropped. A few hours later, I was advertising my Lamms to sell. 

Ended up with a FBP300 which years later is still driving my Soundlabs much to my delight. I don't really have an opinion on post-D'Agastino Krell gear, but those older class A amps are pretty darn special. Cheers,
