Grado SR325is

Hi,

 

Recently my grandmother bought me a pair of Grado SR325is as a surprise. I will mainly be using these headphones in study hall and at home. I am in need of an amp that I can just put in my suitcase or backpack and take along. I was looking at the Grado RA1 but I am not sure if it is necessarily portable. Im in a $350 budget. Any suggestions? Is the RA1 a good match for the 325is'? Is it "portable"?

RA1 is not portable.

 

grado's arent hard to drive, you dont need a super powerful expensive amp for it.

 

and that is quite a nice grandma you have.

So it will be fine just powering the Grado's from the iPhone?

I only have SR60, SR80, MS1 and they do get better from an amp. I use mini3, but you might want to wait for someone who uses the SR335

 

btw the SR335 has a 1/4 plug, that plus the adaptor to 1/8, would make it bulky for portable use

Knowing how whiny people are in my study hall, I do not think I should take the Grado's. They will probably leak too much noise. Mods can you close this thread?

Hey there Leicamaster,

JDS Labs CMoyBB uses the same circuit and equivalent electronics as the RA-1, for about $60 you get a decent portable amp. I've been A-B'ing my 325is's against my friend's RS-2's for the past week and prefer the 325is's for most music. My preference tends toward the 325's with the tape mod then the RS-2's with either unmodified bowls or the TTJV Flats.

You can definitely use the 325's without and amp but the amp increases the sound field and extends the bass a bit.

Wow, talk about an inexpensive portable amp!  It's $33 with shipping?  Sounds like a deal (as long as it performs well).  What are your impressions?  Any issues?

No issue. RA1 is supposedly simple enough to build. If amataur can build a CMOY I guess it is not difficult for a electronic shop to clone the RA1 in a proper casing. As to the sound, it doesn't add anything or less anything so I guess it does a good job being an "AMP". I heard the same thing for the Grado RA1 Amp too, nothing more nothing less on the output sound other than ampification :)

I also saw they sell Ra1 diy kits like this, I am considering very strongly on making one myself and comparing it to my jds labs altoids tin amp:
