post #1951 of 2795

I think Stax just finished a batch. I noticed that Fuiya Avic actually had them in stock too rather than just order.

God, that would be pretty horrible, getting the headphone first and having no way to power it... went through something similar this Christmas when I got a TH600 and didn't have my 3.5mm adapter anymore.

+2. Tell me about it. I took delivery of a KGSSHV and realized I have no interconnects from my DAC to the amp. Cooling my heels for about two weeks until my cable is sent.:mad:

For example, here's a McIntosh MC275 power amplifier:

And here's a Hyperion HT-88 power amplifier:

 

 

Those wide deviations from flat frequency response of tube amps come from interactions of their output transformer / output stage / amount of negative feedback employed with the impedance variations in speakers.   These particular curves look like the kind of "simulated 3-way speaker load" curves that Stereophile runs.  Depending on the design, one tube amp will have greater or lesser "sensitivty" to speaker impedance than others.  It mostly comes down to Ohms-law kind of interaction between the source impedance of the tube amp and the impedance curve of the speaker.  Speakers have crossovers,  lots of drivers and so on, their impedance-vs-frequency curves can be pretty hairy.  And remember impedance is a vector quantity, not scalar....

 

Solid state amps do not exhibit nearly as much of this interaction, mostly because their output source impedance can be REALLY low.

 

With a HEADPHONE AMP designed to drive electrostatic headphones I doubt you'd see much variance of output vs. frequency.  Headphones of all types - including electrostatic- don't have anywhere near the impedance excursions that speakers exhibit.  So "tube sound" in an electrostatic headphone amplifier is more likely a result of harmonic distortion "flavor" than of frequency response variance.  All amplifiers distort, and tube amps tend to have a lower amount of high-order harmonics in their distortion products than solid state amps, many people attribute the 
tube sound" in part to this fact.

 

By the way, using a given set of speakers with a given tube amp can end up with less than great sound, for reasons noted above. The resulting frequency response might be pretty funky, matching speaker to amp can be hit-or-miss.  But I also heard a pairing which made the speakers sound GREAT>  unexpectedly so. Kind of a roundabout way to add an EQ curve to your playback chain, but the frequency-response artifact introduced by some tube amps can compliment certain speakers.  I put a pair of little Polk RT25i on a budget Audioromy FU29 tube amp and I could not believe how great it sounded.  The Audioromy FU-29 is a pretty decent low-cost amp, about 25 class-A watts per channel, and the RT25i's  are known to be great little budget  speakers but the combination really sounded so much better than I expected that I had to have some musician friends come over to make sure I wasn't imagining things or having a flashback to the 1960's.  They also agreed that the sound was pretty wonderful on the RT25i's with the tube amp, except the bass - already pretty light from the Polk's 5-inch woofers - was really kind of "mellowed out" with the tube amp, and not very "tight."  It didn't sound wooly or flabby, just lacked much punch below 60 Hz and had a little extra warmth around 200 Hz.  Still the mids and treble were just wonderful.  So, "tube magic" isn't about how inherently GOOD a tube amp is, it's more about how nicely it can WORK with the right speakers.

How long it took ?

Ordered on 3/31 as I knew they suddenly got stock.  SR009 went out of 4/4.  But I think times are increasing as we speak.  I think up to 2-3 weeks, but my guess is it will go back to months in a couple of weeks.

Tell me about it.  I think I have KGSSHV lined up (cough S).  Got a great offer from Darin to test out that new Vostok.  Looking into it now.  Waiting on the upgrade kit for Perfect Wave DAC to Direct Stream.  Just starting my wait on the BHSE unless someone backs out and Justin blesses me with one.  All in all a lot of waiting.

Very fast.Some members say they had to wait 3 or 4 months.

Justin has them as "in stock" at headamp.
That's where I bought mine from.
post #1960 of 2795

He told me it would be about 4-5 month wait for mine...maybe this has changed??

post #1961 of 2795
I dont have them

I dont know what is going on with stax in north america. I just order and wait

I think they sell out pretty quick. I posted less than 24 hrs ago that Fujiya had SR-009s in stock. Checking now, it says "Sold Out". I'd guess it's the same story overseas too.

Really? They sell out that fast?
I shouldn't have a problem to buy one during the festival in May, should I?

If you don't mind, I'd like to PM you closer to the date to get some tips on that.

I wouldn't bet much on you being able to pick up some 009 on the way back home though. Reserving before hand would be a more reasonable bet...
post #1965 of 2795

Pretty much what Arnaud said.

 

So today I popped by Stax with another HF member on visit to Tokyo and we did see that SR-009 in the glass cabinet. It was wrapped up and there was a sticker on which I believe says it's reserved.

 

I'm going to speculate that most likely Fujiya had quite a few pre-ordered and when the batch came in, they had a spare or someone cancelled their order and put that up on their web page a day back. However Fujiya also tweets whenever they have something special like that available so any followers who are interested would probably call them and order them quickly.
