Soundstage in pure direct not so good

[Tuhin Lavania]

I think the prices are fine. The A52+ retails for 3.26L and Emotiva prices are okay too.

I think the primary reason was cost and second was one less thing to deal with.
After this decision was made, the "pure signal" spin was invented for marketing/justification.

Would this make a stereo system complex? Many audiophiles advise to keep things simple.

Most of the time stereo amps used motorized volume pot which is not digital way.So input signal is not changed or processed..
AVR is works differently-

Analog input to AVR but volume control is digital?

Hi All, Just plugged in CD player to my AVR via analog inputs to use my CD player's DAC. However, the volume control on all AVRs' is in the digital domain... ...so am I right in thinking doesn't matter what people do with the outboard DAC that costs £200 or £2000 when it's put in to the...

If you are referring to slider type analog potentiometer volume control, I think they are obsolete now and can be found only in antic amplifiers. Yes some were motorized.

Latest trend is digitally controlled analog volume control. It is actually chip of resistor ladder network are switched using CMOS switches. Basic principle remains same i.e. analog voltage divider using two resistors. Input to this chip is analog and output is also analog. Output is scaled and given to power amplifier. Following is quote from the link given by you.

Quote:
"I believe the volume onboard AV receivers is digitally controlled analogue volume control? This type of digital volume control can also be found in quite a few stereo amplifiers too. They normally use a specialised IC with resistor ladders switched by CMOS analogue switches. This is still not as pure as pure analogue volume control, but does negate the need for a DAC in relation to its use. Its basically the attenuator that is digital and not the signal it is governing. In fact, in theory a well designed digital attenuation will not cut bits and is cleaner than an analogue controller which can add distortion and colouration. You should theoretically get a cleaner signal via a digitally controlled analogue volume control?"

Having said this, some DAC chip has built in digital volume control but is unlikely in AVR as it has mixed input analog and digital. Pl. note in 'Pure Direct' mode analog input bypassed DSP and given directly to power amplifier, still we can control volume is a proof that it is digitally controlled analog volume control.

In 2ch set up I have set sub mode to be sub+mains. So even while playing 2.0 contents the sub should work in pure direct mode. When I play 2.0 contents from shield it works. But when I play songs using airplay from my iPhone it doesn’t. What can be the reason?

Dear Fm’s

During my entire HT journey I have never given interest to stereo but after purchasing 4500 it really got me addicted especially in pure direct mode.But recently it sounds very bad mainly due to the reason the bass is so muddy and flat. There is no thump or punch at all in the z3. I would like your opinions on what can be the issue. There are 3 possibilities and that the problem is with avr or the speakers.The 3rd possibility is which I highly doubt is the reason and it’s after I installed 65 inch c9. As you can see in the image below when I had a 43 inch tv the speakers were not so wide apart and also had enough room around them. For installing the c9 I had to move both the LR 2-3 inches apart. Now they are slightly wider but as you can see there is no breathing space in the sides as they are almost kissing the c9. Your thoughts on the subject please

What inverter/ups you are using?

I don’t use any inverter/ups for my system. Just connected them to a vertex servo stabilizer

Very true. One of the relatively recent integrated amps which looks comprehensive with controls though on the expensive side is the Parasound Hint 6. It has the tone controls with dedicated subwoofer connection with a crossover knob which truly helps people with small bookshelf fronts looking for good 2.1 music.

Marantz is among the few mainstream amplifiers that retains tone controls, and a way to defeat them by the 'pure direct' switch. The PM8006 even has a midrange control, possibly the only model with the feature. This was one of the reasons for my purchase. It does help me with my listing room's bassy character and can tweak a lot of poor recordings.

It's a good thing to always have tone controls for poor recordings imho.
Does the midrange knob on the Marantz accentuate vocals clearly ?

I have not fiddled with the midrange. I generally use to tone down the bass when it starts shaking the house and occasionally accentuate the treble as my Wharfedale speakers have marked HF roll off. My QA speakers are much better and require less tweaking. I'm planning to change my speakers to better ones and expect much less tweaking. PM8006 is a transparent amplifier and bad recordings sound bad, come what may.

I observed that in pure direct mode subwoofer doesn’t work, only L/R works. When we switch to stereo mode, subwoofer becomes active

check if crossover is set to LFE+Main

That's the way all AVRs are designed to work. With Yamaha avr, SW used to work in Straight Mode.

Thanks for information. I used only Denon and Maranzt.

In Denon 4500 u can make the sub work in pure direct. There is an additional 2ch settings and there u need to make some changes. Through shield if I play any 2.0 tracks sub works in pure direct but while I play some tracks using airplay the sub doesn’t work
