Vienna Acoustics Bach Grand

Well, I spread my Bach Brands and changed the toe in. They sound pretty good, although the volume is low right now. Interestingly enough (or not) I moved them without taking any measurements. I ended up with the centers precisely 7ft apart, the center of the back exactly 3 feet from the rear wall and the toe in at about 15 degrees. There might simply not be sufficient volume to produce the mid-bass standing waves but I think they sound pretty damn balanced.

Finding the right amp for Vienna Acoustics Bach Grands was pretty tough. After spending about 13 months with 3 different amps (CREEK Evo; MATANTZ 2235B; ATOLL IN100 SE), I would have to agree with several people who have responded here; these speakers need power. Without enough power, the VA Bach Grands can sound a bit boomy in the mid-low range. I have settled on the ATOLL IN100 SE for several reasons: (1) its a bright and lively amp, (2) its a dual-mono amp, and it gots lots of juice-power, and (3) its not too expesive (1500 Tx-included). NOW... whoa... these speakers sound boss! So my advice is this: these speakers can sound amazing, but you need to try out some lively and powerful amps.

Viennas are really nice.. you should really consider a real amp not some best buy receiver. A power amp+ pre amp. If u use some new garbage from best buy you will always have garbage sound.
Look into vintage amps. High current. Luxman, nakamichi, harman, yamaha, onkyo all had good stuff. I prefer Japanese as they are diligently designed. Not fixer uppers or projects from NAD or adcom. As far as vienna.. best speakers I’ve heard. I have beethovens, and haydn bookshelves. Looking to pick up bachs. They are as they say laid back speakers compare to say bowers and wilkins. Ive heard and owned bunch if bw stuff. I would no doubt take beethovens over 804s bw. In a 2 way speaker in general u won’t hear a super pronounced midrange. On haydns (2way) it’s actually pretty good. Not absent like in say bowers and wilkins dm602 s3. If u like new age, electronica, and listen to it loud then probably try bw.. but u can’t listen bw for long. U get tired quickly from brittleness and "in your face"Ness of the sound.
I’d say vienna is a step up from brands like bowers and wilkins , monitor audio.. (jessica timberlake, bose, bmw of high end) vienna is more like leonard cohen , vienna, bugatti veyron.
People get obsessed by trying to hear new detail. "Oh shet I haven't heard That string sound on my old speakers, these speakers are more detailed.. " thats where bw gets u with aluminum tweeter and blown up thin mid range.  "Detailed". 

I have the Grand Mozart's. I agree that they may have a softer high-end and may add some mid-range bloom. With the right amp its just a touch.

I have to also agree that they have an amazing soundstage. Highly musical with pretty amazing detail. May have less than some in the highs but you can listen for hours. 

Also you need a high current amp. I would also look for more watts than your receiver. I have older Exposure amp with high current and 90 watts a side and they absolutely sing. I agree a better amp is in order. Think bigger power supply. Most people who don't like these speakers don't have enough current. 

The Vienna line has a great sound if properly set up. One of the previous posts talks about using a receiver which is your first mistake..... you should be using a pre amp and amp of the same caliber as the Vienna speakers.... not a receiver.
