Here’s a review of the ‘new’ Hadyn SEs and the reviewer is using an RS520 as his amp.
Its actually a great pairing. I have the original Hadyns (upgraded the XO) that are 25yrs old and it sounds great. I wouldn’t call it ‘end game’ … but its a pairing that you could be happy with for a long time.
I would then like to hear the two in a direct AB comparison.
Versus
The tweeters look damn identical!
I’d say the Hadyn will win out.
IIRC I believe the drivers are SEAS but are then modified by VA.
Although I could be wrong.
The cabinets are solid. In the original Hadyns, the corners have fillets to strengthen them while the middle of the side walls did have a slight resonance when I did the knock test. The front baffle is really thick as is the top. It was light in terms of internal stuffing and I think they could improve it.
My speakers are rated at 6ohm and IIRC they measured down to 42Hz while these go to 40Hz.
Where they could improve is on the XO Parts. Also if they kept the same orientation, they laid their inductors down on their sides and the fields were too close. (So if you stand up and rotate the tweeter’s inductor, you would be better off. )
Note that they may have upgraded the XO, but from what I saw of their Beethoven line, its the same basic XO boards. Also they really soldered the binding posts in so that the board is pretty much stuck to the back plate.
If the XO plates are the same as the Hadyns, you’d be limited in what Caps you could use. IMHO the Clarity Caps PUR are the best option… maybe looking at adding a Jupiter VCap as a bypass cap on the tweeter. While I was replacing the older CAPs, I also upgraded the resistors too. Higher wattage and wasn’t that expensive. Here in the states, I used parts from Madisound.
The SVS units aren’t bad… but I thin the VA will sound much better.
Similar but not the same. (the cover is different. )
The tweeter in the Hadyn looks like a SEAS driver.
That’s right, I just typed it succinctly. I looked at both tweeters and there are differences.
I prefer floorstanding speakers and also have bookshelf speakers on my second system.
I run my main system with pseudo-quadraphonic sound, so the rear speakers are also bookshelf speakers (with bi-wiring), where I have removed the bridges and only use the tweeters to have smaller effects at the rear.
My father had something like this in the 70s and as a young person (back then with a flute 
), I was totally thrilled by it.
Many moons ago I had a pair of decent Epicure towers.
Wife didn’t like them. So that’s when I swapped in a pair of Hadyn bookshelf.
(of course she didn’t like the color so she wanted to paint them and botched that up. )
That was after having them for 20+ years.
So I got a new set of Mon Acoustics Mini s. And then did some surgery and painting of the Hadyns.
Replaced the 20yr old caps. Then the resistors along w reorienting the inductors which were too close and one needed to be reoriented. (This is part of the Hadyn’s weak points.)
The one problem w Towers is that they are very heavy.
I tend to prefer stand mounts over the towers because of this.
There are a lot of options out there… many of them good.
I honestly believe that there is a thing of synergy between components.
Oh, you should stick to the skills you’ve mastered to some extent!
Why didn’t you remove the chassis and let a professional painter do his job on the casings?
First, my wife thought she could do it… and regardless of what I said… she would do it anyway.
So I told her if she messed it up… I’d get to get new speakers. (At the time these speakers were already over 20yrs old.)
So after I got my new office setup… I did break them down, stripped them and then did my try.
I had to rush it so it didn’t turn out great, but look ok.
You can find these speakers used for around $250 - $500 USD or EUR. You would have to spend another $200 on new caps and resistors which will make them sound better. You could add in a dowel to fix a slight resonance issue w the side panels and then add more fill to the cabinet if you really wanted to go all out. A professional paint job would be a lot more and its an option for future DIY speakers…
For me, it was part of the journey, If I didn’t rush it… could have done a much better job and learned a lot in the process.
That was definitely your main reason for buying new speakers. 
You had it all planned out beforehand…
Actually no.
She came to me… I asked her not to… she said she was going to do it anyway… so I said if she did and it looked bad, I’ll get new speakers.
So no downside but not really want I wanted…
But back to the review… it was interesting to hear why he chose the RS520.
Do you mean the sentence in the whole video where he says:
“I use the 520 as an amplifier and source because it doesn’t distort the sound too much???”
My amplifier also stays out of it for the most part and I hear the speakers.
Mike, come on…such empty phrases!
Other amplifiers do that too!
What is so extraordinary about that one sentence???
