Preferably water tight.

I just got the model 1400 with pick 'N' pluck foam and works perfect for them.

75 bucks is rough but when you put in perspective ($75 to protect a 5k investment) it's like pennies.

I bought that model 1400 about a month ago and that parcel and another one went missing and doesn't look like I will ever see it. That's rough.

I have a Stax 407 with a Stax 323A amp. Would a SRM-T1 be an "upgrade" or "downgrade" or just different when used with my 407's? I have never heard any of the Stax tube amps. If the sound is different, can anyone say in what way?

 

I do enjoy the sound of tube amps for listening to speakers.

 

Thanks in advance.

I recently bought the 407 in the 4170 package (006t included). I had a chance to listen to the 323S at length in the dealer showroom before making my purchase. I think it's a great combo with the 407/507. The 006t will give you a slightly more romantic sound, meaning the mids have a bit more richness to the tone and the highs are a little more polite. I actually found the bass to be very close but the 323S wins by a nose in the bass department as it has a slightly tighter bass. If you notice I used the term slightly several times to imply that the difference is not huge between the two amps when driving the 407/507. I also listened to the 007TII but at the price it makes little sense to pair it with the "lessor" headphones. Frankly, I did not like the 007tII very much with any of the headphones.

 

You might want to consider that the 323S has enough power to allow you to upgrade within the Stax line at some point if you wish without the driving need to change the amp. You would not have the same choice with the 006t as it does not have enough power to drive the higher level headphones (007,009). Still, I am enjoying my 4170 combo and I find it to be competitive with some of the best dynamic and planar headphones I have heard or that I own. There is a synergy between the 407 and the 006t and that must be why Stax paired them together.

 

I should have mentioned that if you really want to play with tubes the Woo GES is the next logical step up from your 323S.

post #19612 of 24765

Has anybody compared the 407 to the 404? Is there a big difference?

post #19613 of 24765

I wondered about that also but since the 404 is out of production it seems we must do our own research based on various comments already posted about the 507 vs the 404 and prior reviews of the 404. The 507 and the 407 are basically the same except for the headband, the material in the cable and the earpads (leather vs plethora). In my own testing of the 507 vs the 407 the only difference I found was the slightly boomy bass of the 507 which many speculate is caused by the leather pads. There are numerous comments about a high frequency etch on the 404's which does not exist on the 407/507. I have also seen comments praising the detail, transparency and tonal qualities of the 507 vs the 404. All those benefits translate to the 407 in my experience.

post #19614 of 24765

I'd like to hear 407 vs 404LE vs 507. I'd like to own one of them down the line.

post #19615 of 24765

404LE is a very good headphone with one con : upper mid peak, its like having needle poking your ear drum. The rest I have no complaint. All the good traits of stats are presented well with this headphone

106 is red-red-yellow, which would be 224k correct?

 

118?

 

002?

Spritzer, or anyone who can help.

 

1.  Could you verify the values of the resistors pictured above?  I've tried to decipher the codes, but I really dont trust myself.  this is high voltage stuff.

2.  for resistor #003, is 392k good?  it is supposed to be 390k on your list.

3.  A couple of the resistors values are only available in quantities of 2500.  I dont know how far I can stray from the needed value to get what I need.  In particular, resistors #101, and #104. (910k, and 270Ω).  Could you suggest a couple alternates?

 

Besides these part issues, I think I have everything put in a cart.  almost ready to roll.

post #19617 of 24765

these colors are a bit hard, so if you agree with the colors then...

 

 

106    red red yellow    220k

118   red grey red red   2.8k 2%  but measure it when you take it out

002    brown grey yellow  180k

002    brown grey yellow  180k

Resistor 118 turned out to read 1.78KΩ.  I'd swear the colors dont say that, but whatever.  looks like spritzers guess was the winner.  I'm still trying to figure out where he got the numbers.

 

 

Last issue.  A couple of the Vishay resistors values are only available in quantities of 2500.  I dont know how far I can stray from the needed value to get what I need.  In particular, resistors #101, and #104. (910KΩ, and 270Ω).  Could you suggest a couple alternates?  different brand maybe?  I've been looking at the metal film resistors, but there are a lot of values in the data sheets that are greek to me.  you guys are familiar with these circuits, so recommendations from you are what I really need.  

 

Here's what I have been looking for:

Metal Film Resistors - Through Hole 1/2watt 910Kohms 1%

Metal Film Resistors - Through Hole 1/2watt 270ohms 1%

001  1K/1W

002  180K  hard to tell from the pic though

003  390K

004  3M3

 

101  910K

102  3K

103  27K

104  270R

105  22K

106  220K  Looks like red-red-yellow but I can't be sure

107  20K

108  270K

109  20K

110  39K

111  39K

112  100K

113  220K

114  3K9

115  39K

116  220K

117  220K

118  1K8  if maroon - silver - red

119  100R

120  100R

121  150K

122  150K

123  150K 

124  150K

125  27K/2W  594-5093NW27K00J

126  27K/2W

127  27K/2W

128  27K/2W

 

All the resistors are 1/2W except where noted.  I like the Vishay CCF for this stuff and they are easy to order.  Just search Mouser with this 71-ccf60 and pick the correct value or the one closest to it from the drop down list. 

I realized today that these are Half of the resistors for the amp.  the 100's resistors.  I assume I am supposed to be replacing the 200's as well?  So doubling most of the parts?

post #19620 of 24765

Yup, I only did one channel so you need double the amount of 100 resistors.  The 00x are singles so you only need that amount. 

 

On those resistors it's hard to tell the difference between red and maroon hence the confusion.  I guess my younger eyes won out in the end... wink.gif  For any extra resistors not available there are always the Xicon 1/2W lineup.  Try this link:

 

http://www2.mouser.com/Passive-Components/Resistors/Film-Resistors/Metal-Film-Resistors-Through-Hole/_/N-7gz41?P=1yzp15y&Keyword=xicon+metal+film&FS=True

 

Given how the part number is made up then this appears to be the only easy way of picking them.
