Any Audiophiles on here with me?

[Kyle]

Wondering if anyone here is into high quality audio, home theater etc. For christmas i got a pair of BIC speakers and they sound amazing! Best speakers ive ever heard, even better than my Klipsch home theater system or Bose!

I bought some vintage components for my man cave. Realistic STA 2000D receiver , Infinity Qb speakers, on your cd player

Rocking a 1992 Alpine head unit with some premium Pyle el cheapo door speakers in front and 1992 Alpine 5x8's rounding out the back of my wife's 1991 Daytona. Sounds like ****---this is the only time I actually prefer NOT to have the stereo on!

I just sent my Denon AVR 4308ci out for repair, the right front speaker was real scratchy and would cut on and off. I feed this mostly with Apple TV (Netflix and iTunes content) and from my BluRay player. My main speakers are DALI 310's, had them for many many years and still love the way they sound.

 

[Kyle]

What kind of sound quality are you getting from the Apple TV? I was thinking about getting one!

I run my Apple TV through my Denon receiver and the sound quality and picture quality are great. I use an old set 7.1 Harmon Kardon surround speakers. AirPlay also works great to stream my audio or video from my Ipad or my IMac.

I've got a pair of Dali IKON 7 MK2's that absolutely blow a way anything I've used in the past.

 

[Expendable]

I love crisp sound but only have two floorstanding Klipsch speakers.

for headphones I have some Sennheisers.

Plenty good enough for my ears

Very cool!!!! DALI is not a very well known brand but they do make good products

 

[M22KLARS]

Yeah I have a good friend who does low voltage for a living and he's very in tune with whats what even the lesser known stuff. He showed me a few different things and I had to have the Dali's.

I used to have a set of Martin Logan Aerius i's, but Todd stole them from me. I used to build tube amps as well... haven't done so in a while, but I will probably get back into it when the K5 is done. I'm gettin' too old to work on trucks all the time

Best sounding amp I have ever built used the now-discontinued SV811-10 triode in a single-ended configuration. Here's a pic of said tube:

When I get back into it, I have a couple Russian GM70 triodes I intend to use to make a pair of SE monoblocks:

That amp is not mine - I posted it just to show what a lit GM70 looks like. It is the large tube on the left.

Here's some more cool amps. This one uses what appears to be push-pull 807 transmitting triodes. The small tube on the right is a twin triode, used as the preamp and phase splitter/driver, and the two tubes in the rear of the amp are full wave vacuum rectifiers:

This amp is an SV811-3 driven by a Russian 5881 and EF86 pentode:

This is a Manley Stingray, which is a stereo amp using 4 EL84 (aka 6BQ5) pentodes per channel:

These are KT88's mounted upside down, which is typical for a guitar amplifier (this is a Traynor YBA200). You will often see a deep blue glow on the inside of the glass of many power tubes. This is caused by high speed electrons (400eV or more) colliding with the glass, causing alloying elements in the glass to fluoresce. Besides their spectacularly awesome sound, the cool appearance is another reason I like toooooobs!

Here's another amp with blue glow, this time from a pair of Western Electric 300Bs

Here's a stereo SE GM70 amplifier:

Some guys build gear with truly vintage tubes. This is an 801A (back) driving a 75TL(front):

Power supply uses a quartet of 866A mercury vapor rectifiers in a full wave bridge configuration. The liquid droplets on the inside of the glass near the top are drops of condensed mercury:

Here's an 833A transmitting tube. At full power, the plate will glow red. You can see the red spot in this pic. Remember, vacuum tubes have no air in them, so the only way they can dissipate heat is via radiation:

Here's an amp using 6C4's driving 1625 transmitting tubes. Again note the blue glow caused by electron collisions with the glass envelope:

Here's a pic of some SED El34's in operation. Note the blue glow on the interior surface of the plate (anode). Again, this is fluorescence caused by high velocity electron impacts exciting elements in the metal:

You can see the same from the interior of this SED 6550 beam tetrode:

Here's an Eimac 450TH running at full power:

Here's an amp using a bunch of old glass. Drivers are type 56, outputs are 71A's in push-pull, rectifier is a type 82 mercury vapor unit (center rear), and the the tubes front and center are VT105 glow discharge regulators:

 

[MaxPF]

Here's a Philips industrial tube running at high power. The filament is made from carbon-coated thoriated tungsten, the anode (glowing red in this pic) is made from graphite, and the envelope is made from borosilicate glass. These tubes are designed to run continuously at high power levels.

None of these large transmitting and industrial tubes were ever designed for audio use, but a lot of experimenters like messing with them and have found that they work quite well and can produce excellent sound quality with high output power. They also keep your living room warm on cold winter nights

Wow, a complete catalog of obsolete electronics components :-D

There is nothing obsolete about tubes when it comes to the reproduction of music. Tube audio is a thriving niche industry.

 

[LagunaH1]

I was kidding

MaxPf thats an amazing collection of equipment! I want the Manley Stingray, that thing is awesome! i might have to get an old school amp like one of these, there awesome!!

None of that equipment is mine - sorry if I implied otherwise. I was just showing some of the cool projects that are out there.

Keep in mind that modern production tube amps aren't really "old school". Although they use tubes as active devices rather than transistors, they benefit from the advances in passive components (i.e. capacitors, resistors) and manufacturing technology. Most of the reliability issues that old tube equipment had was not the fault of the tubes, but rather the resistors drifting out of spec and capacitors becoming "leaky". Either failure would run the tube out of it's specified operating range and shorten it's life. In a properly functioning circuit, power tubes have lifetimes in the thousands of hours and preamp tubes in the tens of thousands of hours. When you consider the lifespan of disposable modern consumer electronics (whether by failure or obsolescence), you realize that a well built tube amp can last you a lifetime

I have some tube amps....... for my guitar.

I have a set of Boston Acoustics (from the late 90s when they were in their prime). I got in to BA in car audio and just love their sound. Unfortunately they have been packed away for a few years since my Sony ES receiver (also from the late 90s) died. I don't have time to enjoy them like I use to and getting a new receiver has been on the back burner. My wife asked me move them out of my son's closet a few weeks ago but I don't think she realized it was going to cost a receiver to make that happen. :wink:

I love 70's silver hifi

Wondering if anyone here is into high quality audio, home theater etc.

Home Theater is a 6.1 using a pair of Klipsch KLF-30's as mains, KLF-20's as surrounds and KLF-C7's as a center and another as a lone rear (all from the Legend series). Klipsch sub.
The studio has Alto 10" speakers (600W) for the PA including a 12" sub (600W) and using an Alto ZMX862 passive mixer. Mic is an EV N/D767a and a TC Helicon Voice Live 2 vocal processor. All connections are via Mogami cables. A vintage Sound City Concord combo tube amplifier (with 2 12" Fanes) runs the Hagstrom Viking Tremar Deluxe. Pedals are a Fulltone OCD, Line 6 Tremelo, Boss Reverb and a Line 6 DL4 Delay Modeler. An Alesis SR16 drum machine carries beat duties. A mint pair of Electro Voice 100A Professional Studio Monitors provide feedback. Acoustic duties are handled via an 80's Ovation Legend 1717 with Adamas strings (.010's). Also use Adario nickel (.010's) with a wound 3rd for warmer tones.

On the purchase list for this year is a Shure SM-7B microphone for vocals.

Had lots of speakers over my many years (Fisher, Bose, Polk) and I like the Legend KLF's very much.
