Should I sell my accuphase for this schiit

@erik_squires its all too expensive for me, but it’s my drug of choice and I gotta feed the monkey. 

@mikem i really like my freya+ preamp and my gungnir multibit DAC so I feel like a pair of aegir will make a sweet set. 

@jond i do wonder how an accuphase from 1974 stacks up against current tech. The accuphase definitely looks good too. 

@georgehifi so if I use the schiit in mono, you say I’ll take a big hit. What does that mean?
  Also, I asked the speaker designer at ascend acoustics about bi-wire when I had them made, and he swore to me that it’s a scam (bi-wire), it has no benefits, and was just created as marketing. So I believed him and didn’t get that option. 

@213runnin @georgehifi  I asked the ascend acoustics designer about the efficiency. I told him I was considering using a pair of AGier monoblock and he had me send over the specs. He’s response was “get the monoblocks, it’ll be no problem”... I’m glad I have y’alls input. I’m thinking I’ll stick with my accuphase. 

@georgehifi  so I wrote schiit about bridging the amp:

It was suggested to me that when any amp is bridged to go into mono it takes a hit as far as
“Distortion is higher
Output impedance is higher
Damping factor is worse
Not as stable into low impedance’s
If it was just stable into 4ohms it won’t be bridged
Current output is worse
And there are a few others I can’t think of at the moment.”
I’m considering a pair of AGier monoblocks. What you thought on bridging these amps

Hi,

The amps aren't bridged when run in mono - they run a single side of the topology, thus avoiding a lot of problems typically associated with bridging. Should work great as long as the speaker are 8 ohm nominal and still fairly efficient.

Best, 
Grover

@georgehifi i learned something new today, thanks. 

@jcarcopo really? I thought accuphase was well respected quality gear ? I’m new to schiit, but everyone seem to think is great gear at reasonable price points 

@cakyol the amp was gone over and restored by Ft. Worth Audio in Fort worth Texas. These guys have something like 90 years experience between them. They’re highly regarded. 

@cmc2234 I’m not sure that bridging the amp is a problem either.  

@georgehifi remember we covered that the Sierra2ex are not setup For bi-wire. I’m not sending them back and getting them to customize it. Maybe they would send me a new posts and crossover and I could pop it in. If I did that I would just keep the accuphase for the bass instead of buying a Vidar BUT... because the RAAL tweeters are the part of the speaker that needs the watts (I think I just made that up) I don’t think the aegir would work anyway. And plus.... putting in a passive switch and all that just seems like more schiit in the signal path. I mean in theory ok it works, but.....

@b_limo what do you mean? I’ve sent an email to the speaker designer at ascend asking about new crossovers and posts... no response yet. I get that george is great, but I’d still have to do surgery on my speakers to make his idea work. Schiit did say when you run an aegir in mono it’s not bridged.. it’s true monoblock. I think George has a neat idea but as far as the question of selling my accuphase I don’t think I should at this point. If anything I’ll wait to hear back from ascend about speaker surgery 

@b_limo @georgehifi  
here is my response from dave... the guy who built my speakers. 
Hi Andrew,

Thanks for the inquiry and I am happy to hear that you are enjoying the Sierra-2EX!

We do not offer a kit to convert a speaker into bi-wire/bi-amp ready. Doing so requires extensive modification to the crossover, as well as drilling and installing another set of binding posts into the cabinet. Also, using 2 different amplifiers for the same speaker is not recommended. If you were going to do this, it is important that the amplifiers used are 100% identical. The term bi-amping gets thrown around a lot these days - often without any understanding.

Hope this helps!

Good Sound To You!
