Last week I have a privilege to audit Winthur new setup with 2 additional 10" DIY Subs. This was my 3rd visit to his place...
I remember my 2nd visit to his place with some re-align of speaker placement plus some tweaking on 2 18" subs the bass i feel can go much deeper and with lot of rumbling... his surround sound & bass had definitely improve a lot after my first visit.

This time with just 2 additional 10" subs... he has bring his bass to another level... this time the bass not only go deep but also play cleaner and tighter plus the rumbling feel.... this kind of movie experience is where you don't get it from the cinema... 8)
For those members who had visit him once should pay him a visit again.
Thanks Winthur, i enjoy every moment of your demo session.
Cheer!

Thanks Kennyluck2000 for the kind words. Could not have done it without the comments, feedbacks, constant questioning and answers in order to reach where it is today.

not only to kennyluck2000, but also to other members who had spent precious time in visiting my humble nest for audit.

still a little bit more to go before doing another Open house again after the arrival of diffuser panels arrive :)

Thanks all once again

yah agree with you Kenny bro.

Today happen to visit Winthur the 3rd time in a row. Got some solid stuff from him.

My Jaws drop.... The " presence " is really good.
The up front Dual 10inchers mid range drivers did perform with solid good quality bass
My thoughts as below:

1. The Twin 10 inchers sound natural and " felt " punch. :)
2.Have never heard such a dual combination DIY 10inchers
   which Mids bass up to par or even > than some 12" subs out there.
3. The back 2 18 DIY inchers will rumble with Wind. :)
4. Driven by Model NX6000d Behringer power amp ( Channel A &B ) , they look really outstanding.

Really good job Winthur. V enjoyable session thumbs up.

Outstanding Amp :)
Saw on web this power amplifier delivers 3,000 watts/channel into 4 ohms or 1,600 watts/channel into 8 ohms,
giving you plenty of headroom to work with.

Ok... i finally had time to do calibration last night using the Marantz MM8077 power amplifier. I bought this power amp due to the following reason:

1. Testing, since i've seen quite a lot of review that this power amp is match make with marantz AVP and since i am using one, i would like to give it a try

2. Sound signature, to prove that is it indeed "heavenly match"

3. Additional channel, the more the merrier even though not using, who know i may need in future? :P

The specs can be found here https://www.us.marantz.com/us/products/pages/ProductDetails.aspx?CatId=avseparates&ProductId=MM8077

The channels are pretty pack to one another to be honest. As compared to the previous emotiva XPA 6 Gen 3 which i am using which are pretty spaced out. The Marantz has a left right switch vs a flip switch on the emotiva for balance and unbalance input.

The binding post seems a bit flimsy but it does the work if you using the banana plugs which i believe most of us do.

It has a little cooling fan on the right which i am not sure if it is even activated, since i am using the AC infinity T10, the temperature does not go as high as emotiva is what i notice despite playing at high volume.

The sound (Audyssey with dynamic vol and dynamic EQ off, marantz power amp for all floor speakers and emotiva for all heights speakers):
In my personal opinion, the sound is not as harsh when playing loud. using SPL meter playing at 80 to 85db ish, the volume from my marantz 8805 is around -14 to -13...which is already pretty loud.

For Movies, what amaze me is despite playing loud, the clarity, dynamics of high and low and the surrounds sounded liquid smooth and clear. Tested incredible hulk and john wicked 2, the sound is so clear and smooth, it is precise and i trust that at certain scene, some details i do noticed with the marantz but not the emotiva...or maybe it's just me for not noticing.... example, you can actually hear something when reeves is walking in the tunnel before meeting the lady whom showed the middle finger before the gun fight starts.

For music, all i can say is it's undeniably excellent! I can say they (MM8077 and 8805) is made for each other! May be there are better power amp out there which i've not heard or tested in my environment before but i can say that for now using 8077, when playing vocals and musical, maaaaan it just sound so pleasing and good! it's buttery smooth, no fatigue at all, listening at -23db is just right for my room. some tracks which i've played became even more lively, music sounded coming from surround sides and overhead but its actually stereo. For the first time ever i swear my Mrs actually commented about my gears saying "how come this track sounded so nice now?" We sat on the couch and listened for about 3 hours until she fell asleep.

I am not sure if emotiva sounded distorted to me when playing high volume but after a movie with emotiva at -15db and music at -22db, it does gives a little fatigue at the end. Do note that my dynamic EQ and vol is off.

During the audessey calibration pulse sound (pew pew pew), i do noticed that the pulse marantz gaves is like "smooth, taking its time, no hurry, soft," kind of feeling. The emotiva is like "com'on let me give all of it, i have lots to give, chiong arrrrr" kind of feeling LOL. But overall after the audyssey, all volume definitely balance out, which eases my worries for a bit. My guess is since emotiva is a USA machine, it should be more daring in producing anything.

Its not that emotiva is not good, emotiva is definitely showing that "look, give it to me and i can do more" kind of feel. i guess my preference just changed from hearing all action and loud, to hearing the details but at the same time loud. i enjoy more details now despite at low or loud volume. :) The watts does plays a part i agree but after calculating the distance, the 1w/1m and sencitivity of my speakers, it may not require so much of a power per channel at the end of the day. Depending at what is being output at the time of moment also.

I'm doing little change, tweaks here and there... as soon as i am done, i hope to invite forum members to my place for some refreshments and enjoy the movie + music at the same time.

I'm more interested in the part after your wife fall asleep.
What did you do ?
Trying very hard to reproduce the music and sound that creative mixing-artists composed in the studios, at home with limited knowledge and resources.
