Pics as promised. She's a beauty.

Unfortunately she is not playing as well with Grados as I anticipated - some resistors may need to be adjusted - but heavenly with speakers...


very , very nice !!

Wow.

 

'Achilles Last Stand" from the Led Zeppelin DVD and the 225i's. Unbelievable!

 

I need to squeeze some time in this weekend and watch both DVD's.

Very nice indeed, sorry to hear that its not playing as well with the Grados, but hopefully you can do some adjusting to suit the Grados.

Out of interest what issues are you having?   I recently built a S.E.X. amp and i'm finding the Grados extreamly sensitive, in the middle of some resistor tweaking to get things dialed in.

 

What is that amp anyway, DIY or something modified beyond all recognition?

parbaked...that amp is just beautiful  :L3000:

 

please report back if you find the synergy for the Grado's.....along with what you did to get them to play nice together!

New glory shot:

 

It was made by Jeff Larson (Abraxas). He usually builds one - offs using odd tubes.

This SEP using 2 6CL6 (6197) tubes and a 6CA4 rectifier. 

Guts:

Believe it or not I don't have enough gain (or dynamics).

I need to turn the volume up to 11 to get enough grunt. 

It sounds like my excellent vintage Pioneer SA-7100 but with the -20db muting switch ON:eek: 

The amp puts out 2.8 wpc 8 ohm into the speaker taps, so it should have enough juice.

I am wondering if it's these resistors are the issue:

^ This is the speaker/headphone toggle box and leads + resistors to headphone jack...

I need to get in touch with Jeff and ask what cans he had in mind, but I think he's speaker-centric from what I understand.

Also curious if I could use the speaker taps for Grados and if so what resistors if any need to be in the adapter?

I never hear of his amps for headphones, always for DIY horn crowd:

This is the amp in the system she was designed for:

CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 75

He's trying to get me to buy those speakers too but I really just wanted a cool amp for my Grados!

Nice looking bit of kit.  In the BH amp the speaker connectors and headphone connectors are wired direct from the output transformer with no resistors in the circuit.  I run mine with the output transformers set to 4ohms (switchable) but i was having issues with low level hum using MS-Pros so Doc suggested adding 120ohm resistors in series with the headphone out which cured that problem. It does however mean i have to turn the volume up for the same output level.

 

Looking at your pic i think those say 330ohm that are wired in series, with two 10ohm in parallel so i'm not what the effective resistance would be.  Best bet is ask the guy who built it, he should be able to advise you on the best setup for those cans.  Basically you may end up dropping down to 220ohm or 120ohm to get the levels you are looking for.

 

Also worth noting its very headphone specific, a stock S.E.X. would be fine with 80i's, but as i moved up to MS1's and then to 225i's the background hum got more and more noticeable. With the MS-Pros it was just too loud. But when using high impedance cans like the HD650's it was barely noticeable, you had to really concentrate to hear it so its all a compromise.

So I bought some 325is's, and they're the shiny chromed versions... I read somewhere (maybe the Grado history thread?), that they were slightly rare because only a few were made within a few months?
Can anyone tell me otherwise? I guess it's not majorly important but I thinks it's cool to know! smily_headphones1.gif

Not sure about them being rare. I remember when the chrome came out...there were two camps...haters and fans. I'm a hater...lol...don't care for the chrome look. Mine are the older goldies which I love. I did see some that were black that would be pretty badazz, not sure if they were factory or custom.

I believe when the 325's where aluminum, people were complaining about the inconsistency with the finish, and also there were some complaints about the finish on the chrome models. I'm not saying that there is a problem with the finish on your headphones (at all), but this is what I understood when I spoke with George at Alessando High End Products (Working Dog), when I purchased a pair of MS2i's, because I asked if they had any NOS in either aluminum/chrome and he said no, and this was the reason for the new sparkle gray SR325is/MS2i's.

Congratulations on your 325's, I also own the 325is's in sparkle gray (which I'm not thrilled with the color), but I got used to it, they are a great sounding headphone, but they are very picky IME with amping, but I do love them, enjoy!

Thanks for the replies :) just wondered!
I think the black ones you saw were the original SR325's, the non 'i' version, they look cool with gold lettering :D

Well i'm hoping for an LD I+ for christmas... that should be ok shouldn't it? 

post #10948 of 17140

When I had my 325is they were also chrome....I love the look and if I ever get another pair they will be chromies!

 

Had mine for 18 months and they looked like new when I sold them.

And what did you amp them with? Your LD I+?
