I like this Roam.
I have the schematics for the Raptor, the fact that one can even get sound out of it is a testament to how forgiving tubes are of inept circuit designs. -
Why would you want to change it? Dr. Shill says it has "the strongest bass of any HP amp."Any idea of what is the best solution to alter the 6210 circuit for the best performance?
-
It's in the head-fi thread, $250 for the mods, $125 for the cheapest cable. You can go up from there to evidently some piece of virgin baby seal unicorn hair for $225. Good god, as someone said a while back all of this is connecting to a 30ga pin at the dock.
-
$375 for the mod package (base ALO cable config)!
Holy sweet Jesus.

Good to have you hear, Young. And don't worry, for the most part we're a gentle and loving bunch.Don't hurt me. My skin is delicate.

Don't know about the jitter specs but it shouldn't matter all that much since my DAC uses an asynchronous sample rate converter that is supposed to greatly reduce (if not eliminate) jitter.Do you know what kind of jitter specs it has? Or is that variable, depending on which clock chip you select?
-
Nah, all their DAC's are NOS-type stuff. The DAC is code named Voldemort, the DAC that shall not be named.So what DAC are you building? Is it also from that site? Looks sweet!
Seriously, when I can post details about the DAC I will.

Thanks for all the kind compliments. It was a pretty brutal build as the instructions that came with the kit were pretty lacking. I would like to take a moment to thank Legos for teaching me to learn visually, without that ability this thing would just be a pile of parts and some pcbs. I hope to work with DIY Hifi to create a better set of instructions as right now I'd be hard pressed to recommend the kit to anyone. The technical aspect is simple as can be (well, mostly) just plug parts in where they go, but taking that stack of stuff and getting it all to fit together as intended was a doozy.
She's small, but don't let it fool you, I'd be the thing weighs in the neighborhood of 20lbs. And yeah, it's redbook only as far as I know.is it for redbook cds? it looks small.
You can find more information on the kit here. The chassis alone is probably worth half the cost of the kit, the remote is milled from a solid chunk of aluminum (no joke) and all of the buttons used are turned aluminum bits.Wow that looks very nice, what's the kit called?
It's roughly 91/2" wide, 3-1/2" tall and 14" deep. I really like the fact that it, plus my DAC should be able to share shelf.that does look great. how big is it?
And Haj, given what your current source is you can hardly expect me to feel for you, right?
-
Well, I'm happy to report that one half of my source upgrade is now complete.
What started life as this:
Is now this!
This all started when I discovered that I knew the owner of HifiDIY through my Millett Hybrid PCB connections. I ordered up a kit and after dealing with the pain that was customs losing a bunch of parts the transport was completed about an hour ago and is now confirmed as working. It's a bummer that for whatever reason it is not compatible with the Denon DAC that I have on loan from Ian but it works just dandy with my HT receiver so I don't think there's a problem with the transport. I'll take some pron shots later with the top cover off if I can stand the idea of taking it apart again. And I'll also be posting a build diary at some point in the DIY forum for anyone interested. Please excuse me, I really must get to work on my DAC!
-
I wonder if there are issues using it without the specified LOD? It would seem to me that if you used another dock, without the decoupling caps, that you could be feeding your amp a signal with large amounts of DC offset. That DC offset, then amplified could easily be headphone lethal. Hopefully when the mod is announced there will be more info about this. I can just see the newbs using their ALO Cryo Jumbo Blamo dock and cooking headphones right and left.
-
I didn't think it was all that bad, I'd rate it "entertaining" but certainly not great. I'd also say that based on what I'd heard going into it I had lowered my expectations.
-
I guess my point was, in a thread asking for a comparison between two amps it might be helpful if you said that you hadn't heard the ppa or that knowing that the two bass boost circuits are identical that your experience had been negative with the M3. You comment reads as if the M3 is the worse of the two. FWIW, I agree with your opinion of the bass boost, I didn't care for it in either amp.
And I retract my statement saying that you speak about things that you don't know about, I have no idea what your knowledge level is.
-
You know, I'm trying to give you a second chance here outside of Head-Fi but comments like this aren't giving me much hope. Your appraisal of Dr. Wells is pretty close to mine of you. On Head-Fi you come across as judgmental, overly critical and like your opinion is the only one that matters. Take the following quote for example:drarthurwells is definately the worst IMHO. After this bizzare incident, I sincerely hope he does not become a member of this forum, or we will soon have another head-fi on our hands.
the bass boost in the M^3 is poorly implemented. it makes the sound muddy.What makes this comment odd is that it was in a thread asking about the M3 vs. the PPA and their bass boost, which just so happens is implemented in exactly the same way. Now luckily enough amb came into the thread and corrected you but this isn't the first (or even second) time that I've seen you post something in a way that makes it read as if you know what you're talking about when you don't.
I guess what I'm trying to say (as I've said on Head-Fi) is that you should choose your words a little more carefully if you don't want to become the second Dr.
Just my 2c, probably not worth that much.

Congrats on the new source! With a little bit of luck I'll be able to post some details of one of my digital upgrades this week. I just finished the last bit of soldering now, all that's left is assembly and testing.
-
Just so you're aware, the good Dr. is ripping you a new asshole on Head-Fi.maybe not the best, but it should be a pretty good amp based on what i've been told. if you make a clone, you have access to better parts so it should sound better than stock.
i've also got the schematics to the Doge 6210, and also my "improved" circuit, which uses the booster triode trick and removes global feedback.
-
Well it's hanging in my living room for starters
Ok, for me the most disturbing part about that picture is the little african-american boy on the left hand side. Dude, even when he hangs out with Jesus he's still starving and has a distended belly. Come on! Wait, maybe it's the little girl on the right hand side lifting her skirt about to flash Jesus... Hmmm, that could be a tossup.
-
Dee,
What amp are you using these days with the 580's? The Melos probably does just fine with them but I'm wondering if you might like them even better from an amp like my HA-2. I find that it mates very well with Senns.
-
Yup.#6, is that Pete Millet?
Pretty sure that's Wes Philliips of Stereophile fame.#12 (the other one, not Tyll)? -
Ken,That little guy would be just the ticket if I could be sure the performance would please me.
I'm honestly not trying to pimp Headroom's gear here but if you're nearly that sold on the unit I'd give them a call and ask them if there was any way that you could get a hold of the demo unit with the expectation that if you liked it you'd buy a new one and that if you didn't like it you'd send it back in 30 days? I have no idea if they'd go for it but it can't hurt to ask right? It strikes me as you trying to save them the hassle of another used amp to sell if you returned a new one during the 30 day window. Just give it a fair shake for what it is, an 8" x 8" box where the DAC (assuming the Home DAC) certainly isn't going to be the better of your $1200 Stello (but might be close) and the headamp, with the Home module, really is pretty neutral.

I don't really want to beat a dead horse here but I think it's gotten to the point where there are so many squeaky wheels that there can never be enough grease. And good luck posting something like this on Head-Fi, the SP mafia will come out in full force.The key is to make enough of a pest of yourself so that he makes the time to work on the amp. This is known as the "squeaky wheel gets the grease" theory of customer service. If you don't bitch enough, he ain't gonna serve you until he feels like it, which may be never, if you call him up every day and go "where's my amp? I want my fucking amp done now or else!" he will break down and get your amp done, and if he doesn't then you fuck him up good on Head-fi.
-
Warm? Neutral? Edgy? How does it drive cans like the Senns and 701s? Guess it's pretty clear that I'm looking for a space saving SS amp for a bedroom setup. Not an easy task IMO. Anyone got experience/thoughts on this one?
Ken,
I think you're already aware of my thoughts on the Balanced Desktop. If not have a look at the featured reviews forum at Head-Fi, my ramblings can be found there. Also, you might try shooting immtbiker a PM at Head-Fi, he spent some time with the amp after I did and he's certainly heard more high end gear than I have.

I think the point was what good is a warranty if your without the amp for 6 months while it's being repaired. Maybe he treats repairs different than upgrades though?the warranty transfers to the new owner.
It's worth noting (as it seems like I'm bashing Singlepower here) that I like Mikhail. We've shared meals and candid conversations so I feel like I know the man in addition to knowing a bit about his business. My general feeling is that he's currently a victim of his success and a desire to please all of his customers. He's taken on way too much and needs to put a stop to it before he does serious damage to his brand.

Biggie,If you don't like single powers service, stop ordering from them damn...
Biggie.
That's all well and good for new customers but the issue here seems to be people that have already paid for services and are not receiving them in any sort of timely fashion. And it's not just as simple as calling your credit card to cancel your order if you've sent the guy your amp to upgrade. And it doesn't seem like calling for an update really works since all he does is placate you by telling you that it's nearly done and should ship soon. The net result is that he gets to it when he gets to it and that's that. I didn't realize that things had gotten as bad as they appear to have based on recent threads and conversations with folks. Not good...

Well, $50 in parts from Digikey and my HA-2 is now back up and running pretty much silent. There is the slightest, and I mean slightest hum in the background but it is so low that there has to be no signal present and you have to concentrate to hear it. WUHOO! My new trafo for the amp should be in next week if all goes according to plan and while that will probably have no effect on the remaining hum I'm hopeful that the new trafo might be quieter than the current one. Now that the hum is gone the trafo noise, that is to say the actual noise that the trafo makes while it's working (sort of buzzish) is now what I hear more than anything. I tell you, living in the country with almost no ambient noise can be awful hard on the old audio system!
