Birgir, are all the 717's prone to fault?

 

[spritzer]

All amps can break down but this the first issue I've ever known about. I just cycled the power on my unit and it worked instantly so it may just have been a Monday thing...

Also, I'm using the SRD-7 from the Speaker B outputs, so having speakers plugged in to the SRD-7 itself is not necessary since it's the only thing on Speaker B. All my other speakers are on Speaker A. Would this affect anything?

How many speakers do you have plugged into the A set of outlets? There should only be one and A should be off when B is on.

Otherwise it sounds either like 1) an impedance mismatch between the power amp and transformer. Is there an impedance output switch? Or 2) everything's ok but your phones have a treble peak which enhances hiss.

The only problem I had with my 717 was when I first got it - it powered up and immediately blew a fuse. replaced the fuse and no problems since. Maybe a faulty fuse? Hope your amp is OK Spritzer. Maybe your line voltage browned out?

No fuse issues since the amp powered up and the bias supply was working but there was no sound. The only time the power system here would ever come close to a brown out is on Christmas Eve but it will never happen, the built in overhead is so immense. My unit also has the original fuse for 100v operation so it is at least 2.3 times too big.

Spritzer, by dint of garnering the most nominations, and if we are honest, for being the most ardent Staxen this side of Miyoshi-machi, takes the ES-1.

Birgir is also well qualified to diagnose ES-1 issues and disseminate such knowledge to other owners.

Congratulations then to Birgir.

Many thanks to those of you who took the time to weigh in with your nominations, I appreciate it.

Very generous of you Afrikane, Birgir has done a lot for the Stax community

I would like to applaud both your choice and generosity.

Spritzer is the man! Congratulations!

That is very cool AfriKane!
Congrats Birgir!!!

Congratulations to Birgir. I had an extended listen to MIKEYMAD's ES1 at CANJAM with the 007, 007A and Sigma/404 and his was a very sweet amp. As I recall he had Mullard tubes (not too sure what these are though).

Three things really struck me:

1) the effortless handling of high volume treble (compared to my 717), what was distorted on the 717 was clear on the ES1.

2) the remarkable differentiation of the source instruments or voice vs the ambience. In visual perception one would talk about "figure" vs "ground." In other words one had a very clear ability to hear these as virtually separate audible entities.

Finally 3) the ES1 gave better control of the Sigma/404 to the extent that the difference between it and the 007/007A was considerably reduced(John Buchanan please note). The Sigma/404 became almost as much a detail phone as the 007/007A.

Comparing the ES1 to the BHSE, the BHSE had more PRAT. It seemed to have a significantly drier, punchier sound. But I didn't get as much time with the BHSE and couldn't really make a good comparison.

Re: 717 shut-off. Mine did so a few months back. The amp needed to be opened and a few years accumulation of dust blown off the innards. Evidently a thermal protective circuit shut-down.

When I'm in periods of the O2 being the go-to headphone as I cycle through them I leave the 717 on 24/7.


Congrats also on getting the big black amp!

A good day for Head-Fi. Afrikane once again shows his remarkable generosity. And spritzer receives well-deserved acknowledgment for patiently sharing his knowledge and helping so many of us get into 'stats. Cheers to both of you.
