Hi Mike,
I have used the 743 topkit in the D10, too, but think the 744OBAC is a step above, as the TLE2141CA seems to be. (look at headphoneaddicts review: http://www.head-fi.org/forums/f105/i...ml#post6022019 )
I changed the big caps to Blackgates. The D10 is a really great little amp/DAC.
Just switched from the D10 to the Yamamoto (over USB-Monica DAC). The Yammy is simply more transparent, one or two steps above the D10.
I appreciate the look of this japanese amp, it is a perfectly built beau. Even when unconnected it sounds sweet.

Thanks for the Airport informations. I think I have to try it.

Thanks for the D10 info. In total, was the Yammy upgrade a good one for you? I am pleased with the D10, but still itching to upgrade. Wondering what your thoughts are at this point.

Hmmmm, that is difficult, Mike.
There is no way back. (That's wrong. There always is...)
The Yammy is superior to the D10, but sitting at the other side of the room, I use the D10 the most time over the week.
With a maxxed D10 and the HF2 you will have a very good little system.
The Yammy is no energy saver, needs some time to warm up and un-emotionally it is "unnecessary", but nevertheless it is a step closer to (audio) heaven.
You will not miss the Yammy when you havn't owned it. Buy something sweet for your wife or take a Yammy or both. ≈≈≈

Thanks! I tend to use a 1 to 4 ratio. For every dollar I spend on my toys I spend 4 on things for my wife. Keeps things in perfect balance. Based on that, I probably cannot afford the Yammy right now.

 

[mikenyc]

I have decided to spend $40 on some black gates for the D10 and defer the Yammy for now. Looks like a great amp and a no brainer with W1000s. Hope to own it some day.

Hello Mike, the Blackgates are fine. You may try the 744/8201 opamp combination, too.
(Un-)Fortunately
there will be something better or different ..... Yamamoto, WOO, Zana Deux, EAR HP4 ... ≈ HD800, PS1000, T1, K1000 ... ≈
there is pleasure with less than the best.

Woot Woot...just got off the phone with Brian from VenusHiFi. I'm thrilled and estatic about joining the Yammie Family.
Quick questions, besides upgrading the amp with a power cord, what else can i do to get the best performance out of the yammie? burn-in period is how long? If i wanted to roll tubes, what would be the alternate besides the WE408A?
Any inputs would be very helpful. Thankyou.

BTW, im using W1000, W5000, Denon 5000, akg701, grado 325i. Sources are Sony SCD-1, 777es, Opera Cononsance Droplet CDP3.1

Hi, After upgrading the power cord...I suggest looking to the fuse and upgrading that as well. They are related, so upgrading one without the other is a job partially done. There are no worthwhile tubes that "improve" performance (from what I hear, not what I know), but try Cryo'd tubes from tubeworld(?). Happy hunting!

 

[Currawong]

Herbies tube dampers maybe?

 

[rhw]

I have some NOS Philips 408A in my Yammy. Sounds fine for me. Added some tubedampers, too. (Golden Dragon Tube Rings by Duende Criatura - Thermionic Valves - Vacuum Tubes)

 

[SundayDuffer]

thx for the inputs guys. The amp is not here yet, but i will read up on the upgrades matter. Cant wait til it's here. thx.

 

[canyon_john]

I have some skepticism about the effectiveness of tube dampers when driving headphones. Are they not for damping vibrations/microphonics from Speakers pounding out the bass notes? I have not tried them except on my phono amp so I am not speaking from experiance, but if no vibrations, no need for dampers right? Or am I way off here?

 

[rhw]

There might be vibrations from the power supply (50Hz or 60Hz)....

 

[canyon_john]

Yes, makes sense. Thanks...I will see if i can detect sonic improvements with my aging ears.

Has anyone tried the yammy with the HD800? I might have a chance in February but I'm still interested in researching the topic. From a purely technical standpoint it definitely can. I'm just looking for phones to hold me over a couple of years until I can get a STAX rig for big orchestral pieces. My AD2000s just ain't cutting it for that genre.

I can say a big YES to the power cable upgrades. I've yet to investigate fuses because understanding how they work, it's an unlikely place to introduce distortion, but maybe switching them out would let more of my cleaner power through. I was quite surprised at the improvement at getting all custom power cables and a 2 plug Shunya conditioner. Really lowered the noise floor and reduced grain, especially in the highs. Now the ATs seem more peaky to me than ever before.

What a stupid hobby.

I already searched the thread and there wasn't much. Maybe I'll post in the main section if no one bites here.
