Default samsung experiments with "tube sound"

some recent Samsung home theater products have a pair of 12AX7 tubes in a circular container visible from the top of the unit. looking at the schematic of the tube module reveals (actually the tube bases only are shown in the schematic, but it's only a minute's work to draw it out properly) it's a SRPP stage (one each for front left and right). i've seen this on a HTIB system (HT-E67xx) and an AV receiver (don't remember the model). it's really not a whole lot of difference that it makes, especially considering the cheap speakers and the cheap class D amps Samsung uses in these systems, but the tubes look nice....

I would never buy anything new from Samsung. Today this company looks more like "Hit-n-run" company that sells you production that dies, drops you as a customer, and offers to buy more.

I bought laser printer, after warranty period ended it stopped working. It powers on then immediately shuts down with no diagnostic. I tried to get support, and failed. Their website organized such a way you can't find any information how to fix the problem, you can't fill the forms because they lead to pages that either crash, or can't find serial number in their databases, and so on. everything leads to "buy new". Then I found the page where I could enter the information finally, it was a page about feedback and rating. I filled up the form explaining the problem. Few weeks after I got e-mail from non-existing e-mail account ("Don't reply') address stating that my review had not been posted, but thanks anyway for the feedback.
The Samsung printer ended in a dumpster. I bought HP printer, and will never buy anything from Samsung anymore.

The only reason why they use tubes I believe is because people buy things with tubes inside. Period. I would not expect some good quality from the fact that the device uses tubes.

I've had the opposite experience. I have two Samsung laser printers that are 8 years old and running fine. My Galaxy Nexus is a great phone. Having lived in Korea, I've used alot of Samsung, and they're a brand I would trust more than LG.

The tubes are just a fashion statement. I'm surprised they did anything more than hook up the heaters.

Samsung chairman is a big audio fan. He tried to launch a line of high end gear designed by Mark Levinson but it didn't get anywhere.

He also bought Luxman....not the gear, the whole company! Since sold.

I'd say that awareness of tube audio is much higher in Korea, at least in Seoul, than it is in the West. There are still a lot of brick and mortar audio stores are around and they are all loaded with vintage and modern tube gear.

Sure this is a marketing ploy rather than an sonic coup, but it is interesting to see the big boys moving in this direction.

Things change. I also used alot of Samsung equipment. I used Samsung cellphone many years, it was indestructable. Until last month a killer wale splashed salty water on me; the cellphone was in my chest pocket.

Now they are different, their production is different, and obviously their goals are different. "Grab money and run away quickly."
Check their website, try to get some info, or to claim any problem. A big hyperlinked sales ad lettuce, nothing more.

The real reason the mega company SANSUNG is using tubes in its products, is the Shuguang chinese tubes factory is owned by SANSUNG himself.

When I know it, I realise why Shuguang big Triodes tubes(and even 300B tubes) had a long, permanent historical of unreliability...

In my country SAMSUNG and LG do exactly what you said, in all the letters.
And of course LG and SAMSUNG are the first and second place in the consumer complaint public office.

Here the LCD/LEDs TVs from PHILIPS, LG and SAMSUNG are know for break just after the warranty time, this happen since many years and nothing happens with these companies, no even a little fine.

I question this often repeated notion that Samsung owns Shuguang. Shugaung is a huge state-owned business group but they may have cooperative arrangements on some products (not audio tubes) with Korean manufuacturers.

For example, LG and Philips co own a factory with Shuguang.
see: SHUGUANG ELECTRON GROUP CO.,LTD and there are a few more mentions of joint enterprises with LG.

But I'd bet we are talking LCDs and TV/phone parts not 12AX7s.

Shuguang Group owns hospitals, real estate management, logistics, and a large variety of enterprises. In this sense it is like Samsung Group and LG group. Samsung does not own Shuguang.

Here it is...

Introducing Samsung's Tube Amplifier

EDIT Looking further into this, it won't even play FLAC files. It's obviously not being sold to the audiophile crowd so I wouldn't expect much.

I would not be surprised if it starts demanding to buy new tubes with factory added chip that counts tunes, and shuts down after warranty ended completely, like their printers do.
