Home Theatre Upgrade

Recommended Posts

Since our house was first  built 17 years ago, the theatre has had a 110” screen.   At the time of the build we also had it decked out with cabinetry – it was the done thing.  Back then, some were still installing 4:3 screens and a  110” 16x9 screen was close to  the limit of what  many projectors could achieve .

While the screen size seemed perfect for 16x9 content,  movies in Cinemascope ( most of them)   were reduced  by the letterbox bars that are inevitable in this type of setup.  My aim with the screen upgrade was to keep the 16x9 images at what they previously were  and gain some dramatic improvement with movies.    I settled on a 140” Oz Theatre screen .

 

The screen was just part of major upgrade which included painting all the walls and ceiling , upgraded electronics and the most amazing centre speaker.

Centre Speaker is Dynaudio Evidence with RRP of $39K  which I managed to buy secondhand.   It is designed as floor standing centre speaker - I tried it with conventional stands but the factory designed approach gives the best results. Sound wise this thing is nothing short of incredible .  Its resolution, soundstage, imaging and bass completely lifts the whole system.  It blends in seamlessly with the rest of the system . The fronts are Aurum Cantus Grand Supremes .  They also project a large soundstage and have excellent imaging .

It is amazing what flock coating acoustic treatments  can do  to the WAF.  

 

Moving to a Dolby Atmos /DTS-X system meant 4 new ceiling speakers.  I settled on Polk Audio 70-RT from USA ( cheaper than buying locally)

To drive the ceiling speakers I thought I would try a low cost option direct from China from a company called Wentins. I saw these  at the Ghanzhou AV show a few years ago and they  sounded great so I thought it couldn't hurt trying one out.   I bought a relatively cheap 5 channel  @ 200 Watts per channel. These guys make a huge range  and will custom make high power amps to your specs.

I had been using the original NAD  Master series M25 for the system previously  but after trying out the Wentins, it was clear it was doing things nicer than the mighty M25. It had all the speed of the M25 but with a richer timbre  and superior dynamics and bass.    This got me thinking,  if one of their cheapest amps sounded this good, how good would one of their better ones be?    I decided to relegate the M25 to ceiling speaker duties, use the Wentins multichannel amp for surrounds and rear surrounds , and ordered  hifi monoblocks  direct from the factory.

These amps are fully balanced and  produce 225 WPC into 8 ohms and 450 into 4 ohms. ( all speakers are 4 ohms in this system).  They were still well priced  but being hifi  amplifiers, they did not have a  12v trigger which I have since added.  The L&W brand is part of the Wentins group.    These allowed me to run balanced XLR cables to each amp and I'm more than happy with the result.

Nice. I also run non matching speakers but cannot notice any difference. What sort of subs are you running?

Projector is Sony VPL-VW760ES laser projector.     We still get amazed  with the images it creates and the latest firmware has  just pushed its performance levels up again. 

Projector mount is Peerless PRG - superb IMO..

Subs are sealed 2 X Rythmik 12" units  which have their servo drive system that greatly reduces cone movement after the LFE signal has stopped. the result is very accurate bass.

I had the projector calibrated as well as audio measurement/calibration for the system.   I can recommend audio room analysis from this experience.   I thought I had things  sounding good until I heard what could be done after acoustic readings were taken and analysed.     I haven't finished in this area, i have new bass traps and acoustic diffusers on order.

This is a 5KVA balanced and isolation transformer  and sitting on top is a 12V linear power supply .   I use the transformer  to power  the source gear and  Marantz Preamp  so its a bit of overkill for size.  The balanced windings effectively cancel out common mode noise  in the power line.  With my 2 channel system I use an Accuphase power regenerator and I installed the balanced transformer  to see if  I could detect any improvements.   Sure enough, audio has improved and I suspect that most of the improvement is coming from the Marantz 8805.  Interestingly, when I tried the same thing with the Denon AVP-A1HD Preamp, I couldn't really detect much difference which would indicate that the legendary Denon unit has superior power filtering to the Marantz. 

 

The 12V linear power supply powers a Zappiti One 4K HDR SE media player  and the occasional other unit such as Roku.  This is a definite plus IMO for both picture and sound quality.  Comparing Roku PQ to Apple TV 4k, Apple TV is far superior and that is with its built in SMPS.  Add the Linear PSU and the Roku gets a performance boost - still not quite enough to match Apple TV which indicates what a good job Apple has done with the hardware and their own SMPS.  

 

However, the LPSU does push the Zappiti ( and I would think equivalent Dune players)  to a new level. So much so I am struggling to pick any differences  between it and Oppo ( with its own LPSU) for 1080P material. For 4K, Oppo is clearly superior. 

 

I have also a separate balanced transformer powering the projector - It also has a 20V step down  function . I had a bad experience with Perth voltage with another projector and wanted to  avoid any issues.  I haven't detected any PQ improvements with the Sony PJ using the balanced transformer like I did with a Sharp DLP projector a few years back.  So clearly Sony's power management is better than what Sharp's was  earlier on.

Some great gear mate. Would be interesting to know the price of the Chinese amps

 

You run your 2 channel through the 8805?

I have a separate  Magico S7 / Accuphase 2 channel system upstairs.   We do however use the 8805 for 2 channel occasionally - primarily streaming from my music server using Heos. I like the result.

I bought my multichannel amp from this site.  Ive bought a few things from them and can recommend them. 

https://queenway.aliexpress.com/store/group/AV-Amplifiers/1070003_511406315.html?spm=a2g1y.12024536.pcShopHead_12029297.1_3_7

 

 

I ordered this amplifier and was told that they only make a 200W version now (which they sent for same price).  It doesn't look like they've updated the website.

The company makes a big range of gear only some of which is listed on that site.

Now, that is what I call a processor!

 

Just like the rest of your gear, no half measures.

 The Lyngdorf MP50 arrived  and you know they take room DSP seriously when you see that they supply a  professional looking mic with XLR cable and an all  steel Microphone stand.

As to performance -  simply stunning!    I'll probably post more detail - warts and all - in a new thread but in the meantime I'm still taking it all in and  re-discovering favourite movies.

That’s what I call taking DSP into another level, welcome to the club, even if I’m running only its 2channel integrated small brother after hearing what it can do it’s hard to go back 👍

      Hiya - my son came over from the UK for Christmas so I got him to collect and bring back a Sony WM-5 cassette walkman as a birthday present and summer project. It was not working and in far from pristine condition but after considering a variety of different models, I decided I loved the look and design of this model best. The WM-5 is a relatively rare metal model that closely resembles the design of the WM-2 so I've referred to youtube and a digital copy of the WM-2 service manual to work on it. This is my first walkman project.
       
      I could hear the motor whirring when I put in batteries and pressed play but the capstans didn't spin. I suspected the belt had perished and confirmed that was the case when I took it apart. Note that, if you have one of these and want to take it apart, the play/ff/rw/stop buttons can get caught on the very thin aluminium fascia that surrounds them so you have to be very gentle working the body out of the case. Also, take good photos of the inside boards and thin wires in case you accidentally break them or for resoldering them.
       
      I found the original belt had turned to black goo and it took some time to clean it all from the wheels. I replaced the belt with one of similar diameter but 1mm width, which I bought in a pack of belts of varying sizes from Ebay. The buttons seemed to be working so I put it back together and have been testing it. My advice to anyone wanting to undertake this sort of project is to have all the tools, parts, DC power wart, grease and oil when you take your device apart - you don't want to have to take it apart more than once or twice as you increase the risk that something will break each time you do.
       
      I have got it working but I still have some issues to chase down (any help you can provide would be appreciated):
      1. According to the part list for the WM-2, the dimensions of the belt are 44x0.9, which presumably is the diameter and width in mm? I've fitted one that looks pretty close to 44m diameter but it isn't easy to take an accurate measure of the diameter of a rubber belt! I have read that a non-standard belt can cause higher wow and flutter but this belt at least proves the motor mechanism works.
      2. The ff button works fine and the motor action is smooth and relatively quiet but the rw button is unreliable. It will rewind for several seconds and then stop. If you press the stop button and then press the rw button again. It will start the action then stop quickly. Repeating will go back to rewinding for several seconds and then stop. The rewind action is noisy and not smooth. Also, sometimes, after you press the stop button after rewinding/ffwding, the left capstan starts turning for a few seconds before it stops?!
      3. The play and stop buttons work fine except the play action is noisy to my ear (I can't remember how quiet/noisy walkman used to be!) and the noisiness varies metronomically. This might be causing the wow I'm hearing on the tape. However, I only have one tape to test the unit at present (I will locate some more) and while I think I detect some wow it might be the tape (it is an old and low quality children's story recording).
      4. I have ordered some replacement screws for the several that are missing but I can't locate a replacement perspex window for my broken one. I see that you can get a replacement for the WM-D6 but I cannot find anything online to replace what has to be the most common walkman window in existence!
      5. The matt black paint on the case has been scraped off in a few places and I would like to touch it up but don't know what product is best to use.
       
      I have thoroughly enjoyed my summer project so far, and I would dearly love to get it looking and running as well as it did in the 80s so any advice and encouragement would be gratefully received.
