I’ve had that setup (minus the BT receiver) since 2009, when I built the amp and DAC. The next year I left my home city. I’ve moved a few times since then and this setup has always come along. So that always feels homely to me. Depends how quiet you like the room to be. There is the distant...

It sure is

Bumping this thread to say thanks to Dr. Cavalli, cfcubed, and everyone else involved in creating this great little buffered tube amp. It's travelled with me to three different cities and is a fond reminder of my head-fi diy days. Here it sits on my night-table in Switerland, far from my...

I moved from Canada to Switzerland in October and just brought my headphone 'rig' here last week :)

It makes if you think of the financial incentives. DIY amp sales take away sales from commercial companies, those companies are then less interested to spend money to advertise on head-fi, the head-fi owners then make less profit. Of course this is a very simple way to look at things. You...

I've been away from Head-fi for a few years now. Actually I stopped visiting the site not too long after the re-vamp, where the look of the site was changed slightly and a major focus was put on controlling the aftermarket sales of gear - in particular DIY equipment. This was not too long after...

It seems that 3 channel will have some benefits in terms of cancellation of amplifier noise

I am the jerk who's had cobaltmute's r1 for over a year and still have not tested it. I didn't realize how busy my life would be and entering a program at a new school where I don't do anything with electronics has made it difficult to get a hold of equipment. ..okay these are poor excuses.  ...

That new Viablue plug looks awesome.  Sweet looking cable too!

Quote: @civilmonkey Another thing to consider is whether a DACT makes sense in this application.  Considering the CTH uses a single dual triode tube you will inherently have some degree of mismatch in gain between the two channels.  Using a volume control that's intended to track two...

So I guess it's a design choice between having an 18mm cap option and having the option of mounting the heat sink inside the board. To me the latter is more useful and is necessary if you want to claim that the regulator only occupies the space of the board.

Quote: Although it technically fits it's probably not a reasonable build option since there is a good chance of direct thermal contact to the capacitors on either side.   This could be rectified in the production version by moving R3 down, turning it 90 degrees clockwise and moving C3...

awesome!

  Quote: ^indeed it is and my money is fully on this being a joke for these reasons:   1. if you're going to introduce an iem with 20 drivers - which makes no sense from a technical a standpoint - that costs $8000 you'd be damn sure not do it april 1 2. jude claims to hear...

  Before we get started I want to say that:  1.  From a technical standpoint an improvement in the circuitry based on post #1 is questionable to say the least 2.  Cap choice is an area of audio black magic (like so many areas of audio).  It generally defies any kind of quantitative...

Quote: I usually bend the middle lead only

  Quote:        I'm not sure what you mean by star ground since this board has a ground plane.  SG is a point on the ground plane which is connected to the power supply ground.  Also, your case and pot should be grounded to the same point unless your pot is well isolated from the...

  Quote: You're probably having charge build up on your case.  It should be grounded for safety, and this will solve the issue you mention.   Here's how I did it:   fyi the other white wire goes to the pot (to stop hum when you touch the volume knob) like so:

The major source of bulk isn't the circuit but the gigantic batteries used.  If you want small you need to use Lithium batteries.   I think the community generally doesn't like these battery types because they can potentially explode when misused.   In my opinion the smallest you can...

Quote: I disagree.  I find the rs-2 looks better while the rs-1 sounds better.  Serious about the looks - the rs-1 just looks strange on your head because of the long chambers.   Also from what I've seen used rs-1s tend to go between $450 and $500 (maybe a little more for a very new...

Quote: yeah, that's fine assuming it's in focus

Quote:   I'd recommend Amperex 6922 PQ if you're willing to spend the money.  Another great option that is very affordable are GE 5814a ...if you want to spend some more then RCA 5814a. ...and you gotta have at least one actual 12au7...

Quote:   Tube hybrid is definitely the way to go with the RS1i (and I believe the Xcan is tube hybrid).  Personally I use mine with the CTH and the synergy is really amazing (this has been commented on by several CTH owners).  In fact it's so good that when I had to pick one and amp and...
