I am not saying your wrong. I am just saying that this would be false advertising in a big way.
Also found a few sites where they have not cut and pasted and both chorus amps in there specs, list class a ibias technology as there features. So something is fishy here.
Kal Rubinson please help!
You have talked to Bill McKiegan I believe about the new amps. Did he say that the Chorus amps were not class a ibias? Did he say they were class a/b?
I have to say that Krell MUST do a better job of getting information out to potential customers, even if it means having Bill or Patrick visit this forum from time to time.
My first jolt was to learn that my unit is not a 4k unit, which my dealer had told me it was (which he'd heard from Krell). OK, no big deal for me, because I just bought a 65 inch 1080p (non-4k) TV and wanted the lower priced Foundation anyway, and it does have DSD. So, no harm no foul.
But then someone reports that Patrick said the warranty is not transferrable, which is not stated anywhere within the published warranty description on Krell's website. That's not cool.
Now there are these questions about whether the Chorus amps are Class A or Class A/B, with Patrick supposedly stating that they are the latter. And since he's the head of sales and marketing at Krell, presumably he knows. If not, that's another shocker.
And is it just the Chorus or all of the new iBias amps? There is a long thread on the preamp/amp forum over at AudioAsylum.com. The thread was initiated by a guy who was expessing his excitement about purchasing the new Vanguard integrated, which I'd not even heard of but apparently is shipping(!!), but then a number of posters stated that the whole iBias technology is not really Class A at all and is not particularly novel. They also pointed out that the published output current of all of the new iBias amps are a lot lower than the Evolution or older amps were (and in fact lower than many less expensive A/B power amps), and then they claimed that the published current could not support Class A up to the stated power ratings. I have no idea about the ultimate claims, but the published output current does seem low for these new amps compared to Krell's older amps, with the Chorus amps being the lowest. The poor OP in that thread ended up getting cold feet based on all the swarm of negativity and cancelled his order! A perfect example of social media and the internet leading to terminal "audio nervosa". Terminal to the sale of the Vanguard integrated, that is. You can check out the thread - I'm JoshT on AudioAsylum and challenged some of the naysayers, but apparently the OP ended up joining them.
None of this is to say that the Chorus amps don't sound amazing. I am sure they do actually. And who knows whether the naysayers were full of sh#t and just having fun bashing the new Krell and crushing the enthusiasm of a poster? The internet is full of nasty people and trolls and it's not always clear who is who. And, in fact, everyone I've heard from who has auditioned the Chorus amps says they sound wonderful, including a guy who owns one of the top Evolution amps. He thought the Chorus sounded amazing in a demo room driving big Martin Logans. I am still very eager to audition one at some point when my budget permits further upgrades, and am confident I'll be impressed and intend to get one.
But Krell has to address these issues, and in the days of social media they should be doing it here and over at AudioAsylum and other sites.
