Amazingly Close to Krell Sound


Hi,
A few years ago, I sold my Krell KSA 80B to my brother in law. 80 lbs was nothing to a tree climber with his own landscaping business. Well, diabetes has caused huge health problems in the last few years and he's asking me to help him.
He loves the Krell sound. But he has absolutely no energy to move his amp. Each time his health fails further (recently lost a toe) he has to get help moving his amp. (moved from his own home to a large one floor apt. then from there to a floor in his brother's home) Folks don't mind doing it, but that's not what he wants. We've read about the KSA 50 being warmer, and that appeals to him, and he likes the KSA 80b's sound. Here's what we were wondering:
1. ...of the Krell owners, what is the closest company to the Krell sound? PASS? Spectral? Who?
2. How much do the KAV amps different from the KSA amps if there is no answer to #1 as any other amp being close?
3. I'm going to have to sell his KSA80, I'll send it back to Krell for their stamp of approval, and sell it here and have it shipped from there. So what can I get him for about $800 that will be 40lbs and sound as absolutely close as possible.
I'm sure you folks can help me. Krell experience a must for this one.
Yes, I know system dependancy is important, but we'll leave that as a constant, "you've had Krell, you've loved Krell" and go from there.
he's had yamaha NS500's Ns 1000's, VanderStein 3's, and is now running some I built for him with Vifa aluminum dome (like the Vanders) and Dynaudio 7's, polyprope caps with teflon bipass caps and silver clad 6 9's copper wire. Now that he's going with smaller woofers, that tight solid bass is a must. He's running a Krell KAV 250CD and a McIntosh tube FM Tunor, into a Krell PAM-5 pre.
Okay, another post for more help on this, so we can stay on topic. Help... I really want to help him.
Thanks

I can't compare the Krell - but a small SS integrated amp is the PS Audio GCC series. Have it modded by underwood and put in critical link fuses.

It's the best SS I have ever heard - and quite reasonable. The gain cell preamp really makes it shine - however the break in is pretty long.
Aragon 8008B is a killer amp. Very detailed Powerful lows very krell like.
ive owned several Ksa250's Ksa300s MDA300 Ksa200 ect. Get the aragon.
As the krells get newer and newer they keep boosting the Highs and detail, Some like them some dont.
I would second the McCormack DNA 0.5, or 1.0 I have a dna-2
and find krell like bass and a slightly warmer sound.

i put my hands on those DNA 0.5 or DNA 1. I have krells before and while they are good, i find them a tiny grainy. The mccormack is smoother and tube like with details.
Okay, thank you all.
So will the McCormack or Aargon have the bass? Or are they similar there with different musicality?
What about those PS Audio amps? Are they of the same league as the McCormack and Aragon?
