post #10951 of 19373

one day i was curious, and just for the hell of it, i plugged the lcd2's into the little dot, it was good, it surprised my how good the LD sounded

No, I did not own the LD1+ when I had my 325i.

 

I used the amp from my STX soundcard.

Also looking at the Little Dot Dac I... anyone had any experience with it?  A couple of reviews raved about it.

The LD1+ will be fine with the 325is
 
I loved the aggressive sound from the 325's

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:

Nice looking amp, love the red, although I'm not too crazy about the bakelite-like volume knob.  Kind of a turn off, pardon the expression, for me.  Hope you get it to work on headphones.  I would like to read your impressions.

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.

Any hum is a non starter for me.  Sounds like you have something that is not quite right.

I seriously don't think there's a better amp for Grados at the price point. I've read that the Schiit Vali is pretty darn good with them but I think the LD1+ still trumps in the $100-$200 price range. I'd like to try a Schiit amp someday. I'd also love to get my hands on a Woo and ultimately a Dacware. My local Grado retailer also sells Dacware so I've heard Grados on a couple of them and OMFG!!! But I'm not about to cough up $1000+ for a headphone amp.

1. Do you mean Decware?

2. If so, do you recall which models were the best OMFG match for Grados.

Thanks,

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.

Got the schematics and fix from the designer/builder!

The 10 ohm resistors do a pre-load on the output transformer secondary to improve sound in Hi Z headphones.

I just needed to snip out those two and bend out of the sway so I can re-attached if desired.

Also said I can change, or even replace with bare wire, the 330 ohm resistors for more gain but at the risk of noise.

Easy instructions from the builder (so pleased not to have to re-solder anything!):

 

I am all good for now. The amp remains dead quiet and my Grados start rockin' around 12:00 on the dial!

Nice soundstage and imaging and really clean mid range. So far so good!

I dig the bakelite for DIY retro look! My MAD had 'em too but this one is bigger!

 

Fixed the compatibility issue and she sounds superb, even just testing with iPod LOD!

Excellent.  If just removing the 10ohms from the circuit gets you the gain you need i would leave it at that, removing the 330ohms will only introduce background noise which the Grados seem very sensitive to.

 

I basically had the opposite problem as the S.E.X. had neither sets of resistors so i had to add the 120ohms in series.  Its also working like a treat now with ~12 o'clock on the volume being my normal listening level with a silent background.

 

Enjoy :L3000:

Glad you got it working....I also dig the look of the retro volume knob....I dig the look of the whole amp

 

I like this look way more than some of the fancy amps that are popping up....I like old retro stuff.

 

The cans look great sitting by the amp , also.

post #10963 of 19373

Glad to hear about the amp, nice job on the fix, glad to hear you like the sound…and it is real cool looking, enjoy!!!

Yeah, I meant Decware. Pretty sure it was the Taboo.
