Best older Krell integrated amp that sounds good?


I have looked at several "USED" integrated amps, and found the Krell KAV 400Xi gets high marks from reviewers. However this unit was first marketed in 2006-2007, which raises the issue with why bother with an older design, that was replaced 3 years later. KAV-400Xi packs a wallop of power at 200RMS. My concern is: will it be equal to or exceed the performance my Red Dragon M-500 digital mono blocks. I am getting tired of all the separate boxes, and want to make the system simple. I have seen a few KAV 400Xi on AG, but the sellers were asking for too much money. Maybe, I am wrong but the "blue book" price on this amp( VG used) is about $1200.

Of course, my other option is to look at some of the newer integrateds on the markets at or under 1500. But i am looking for quality sound without reaching for A PASS, ARC, Rowlands integrated. My system is not in that league.

Sunnyjim, with all due respect, I have to agree with Rrog's initial point. IME, the Krell integrated amps and KAV offerings are not in the same league as their separates. Now if the your not interested in spending the money for Krell separates, I can understand that, but I believe Rrog was trying to offer you the advice not to confuse them even though they carry the same name. OTOH, a Krell integrated just might suit your needs and values.
To Unsound: I was not putting down Rrog's advice; he is usually right in his judgements about high end audio. The issue is: are buyers getting what they pay for??. After my short audition of the $18,000 floorstander, I thought how do I measure $5000 of audio satisfaction, where does the $10,000 level start, or will I be doing cartwheels nad running down the streets with sparklers in my hand yelling "Eureka" when I have reached the $18,000 plateau of aural satisfaction.

Buying audio is not like acquiring the services of a high end escort where you wake up the next morning and say "WOW" that really was worth the $5000. I think it might be easier to determine the level of one's satisfaction in those circumstances based on dollar per dollar ratio

My intention is not to make light of this issue of value in high end audio, but I think it is easier to find value both monetarily and personally in products that are overachievers, and intelligently engineered.

The same company that sells the $18,000 2 way floorstander, has just released a new model that is a cool $107,000 By the time a buyer outfits this product with comparible electronics and cables, he/she could be at $175,000. I don't know anyone who will make that type of investment in audio. Maybe in places like NYC, Dallas, Chicago or even Honolulu where there are incredibly rich people whose discretionary spending allows that type of purchase Today, high end audio suffers from an economy of scale. It produces audio products removed even from the shrinking pool of upper middle class buyers. In a declining economy, this strategy seems to be even more ridiculous and ironic. How many buyers out there are going to be interested in a $107,000 speaker system. And more importantly, what is the longevity of a company whose least expensive speaker is $18,000, or separates that begin at $15,000 and and top out at $85,000 or $95,000. How many "turns" that is, sales is that manufacturer going to have to make to keep the show going, and for that matter, the brick and mortar Audio shop whose got to sell these products just to pay the rent and utilities.
Maybe the Wyred4Sound STi-500 integrated amp would be to your liking as it uses similar class D technology. If you find one on the used market it would be in your price range.
second Krell kav500i.own for 5 years already,the cheapest way dip into audiophile waters:)
paid $2000 at that time, now i think will be around 1700-1800,not so many appears for sale ,means this quite a good amp.If you will be lucky may be you can get for 1500
