I suspected Shostakovich. Thanks a lot! Shostakovich is dear to me, but so much remains to be listened to

Is it just me or have all the images disappeared...?

 

[SystemaMurata]

Unfortunately...looks like the source of my images changed location

Here is my vinyl rig!

I've just installed SME V with Lyra Kleos:



RIAA not decided yet. I'm going to compare some to choose the best. I'll keep posting about progress.

After all, looks like I've ended up with my speaker system!
So, it is 4 channels:
1. AER BD4 from 400hz and up
2. GOTO 146 in half LeCleach for 100-400hz
3. GOTO 146 in spiral horn for 40-100hz
4. Velodyne DD-1812 for 20-40hz

Updated picture of my setup.

SystemaMurata, have you made any measurements of the AER driver. I have yet to see or hear a whizzer cone produce linear HF.

Regards

 

[SystemaMurata]

Yes, sure I did. The interesting feature is a bump at 10khz on axis. But at angle this bump become smaller and finally disappears at say 20 degrees.
The thing is that this bump you hear like much more live and detailed sound, but a bit too bright. I personally, like bright sound, so for me this feature works perfectly. And if someone like dark, he needs to sit at some angle from axis of drivers.
Regarding bottom range, AER is terrific! It works down to anything
Look at this 2-way system with 2 AERs without any other support of bass:

And this is 3 ways with 21" ported sub low passed at 50hz by 4th order:

And this is my favorite cello concerto with 2 AERs without other bass support.
All recorded to the iPhone 7.

SystemMurata: Remember you need two dual subs.

 

[SystemaMurata]

I don't think so
When this dual sub is crossed at 40hz with 6th order, second 12" driver is actually not working! So, single 18" with cone control feedback is actually enough!

 

[SystemaMurata]

I would like to share my findings in vinyl setup.
Just compared new tonearm from Primary Control with SME V and very much impressed with it! Never thought that bass region of vinyl can be so delicate, tight, powerful and deep! Thanks to Primary Control Arrow Tonearm!

did you really believe you would be able to have a civilized "debate" with Romy the Rat ?

“Never argue with stupid people, they will drag you down to their level and then beat you with experience.” Mark Twain

thats precisely what he did with you.

But the decision to get into the arena was yours....

 

[SystemaMurata]

Yes, Angelo, we are his best friends
I don't care really.

 

[angeloitacare]

well, u actually did, since u called him an idiot as well.

But something he said i agree with. ( Don't know if you realised that already or not )

Audio can become like an addiction. U want more and more, and are never satisfied.

When someone is in this situation, its better to stop. It will never fill a inner existential emptyness.

 

[SystemaMurata]

But something he said i agree with. ( Don't know if you realised that already or not )

Tell me what you agree with. Let's discuss it here.

 

[angeloitacare]

the follow up of my post above.

He didn't say that in your recent exchange with him, but some time back.
