@K_19 - Have you tried your ODAC with your STAX rig. If so, impressions?
That W4S looks interesting, if I had the dosh I'd try it.

Can't say I have yet as the ODAC is always tied up to the Objective 2 as my secondary rig for the K550... I'll give it a shot one of these days though.

Radiohead: That is the most generous offer. I love the way this community pulls together. Yes, I would welcome that arrangement. I have not heard back from him today, but as soon as I do I will get back to you.
AGAIN, THANK YOU ALL FOR THE CONTINUING INPUT. GREAT SUPPORT.
Actually, that amp was listed on Head-Fi http://www.head-fi.org/t/608173/sold-blue-hawaii-special-edition-bhse. Maybe contract the seller to get additional information. Some of the pics on gon look very familiar too.
I am starting a search for a new inexpensive amp to drive my SR Lambda Normal Bias + SRD7/SB. I want it to be somewhat portable. Under $400. What do you guys think of this one? Or do you have any suggestions?
Specifications: • Power output: 15W x 2 (4 ohms, 10% THD), 9W x 2 (4 ohms, 0.03% THD), 10W x 2 (8 ohms, 10% THD), 6W x 2 (8 ohms, 0.1% THD) • Headphone power output: 60mW x 2 (16 ohms, 1% THD), 120mW x 2 (1% THD), 100mW x 2 (32 ohms, 0.01% THD) • DAC THD+N: 0.008% @ 1 kHz • Signal-to-noise ratio: 98 dB • Dynamic range: 98 dB • Dimensions: 4.17" W x 1.65" H x 7.1" D.
I just got my first Stax in the mail today and it is blowing my mind. I have nothing else to say.
Congratulations. When mine first came, one year ago, I remember thinking how this was the first headphone I'd ever heard that sounded, not only like speakers, but like my speakers (Quad ESL-989). It was revelatory. I am happy for you. 

Can't say I've tried that Topping with the normal bias Lamda's but have tried it with my Lambda Pro's, given said the sound is not good. Right now I'm using a cheap Chinese MINI P14 EL84 tube amp (rebuilt and modded) for my Lamda Pro's and it is very good sounding, very dynamic and fluid with great depth with the lows and soundstaging better sounding compared to when I had them driving off a SRM-T1. Although not very portable and EL84's (7189, 6BQ5) tubes tend to run very hot (x4 + 2 6N1's).
I had a pair of DA-100 driving my Martin Logan CLS IIz, excellent sound. They put out the same amount of heat as a good domestic heater, it got quite warm in my room in the summer.
Now I have a pair of big Maggies driven by EAR 549 tube monos, the CLS just couldn't play loud enough for my taste ...
What happened to the DA-100?
I'm looking for a nice pair:-))
Regards Georg

Thanks for the feedback. I think I'll keep looking around.
How much does a Stax Sigma Pro usually go for?

Nice ! Very interested on hearing the modiified 007t series . Hope you can bring one to the CHANG-fest. :-)
I think this is the first and only time I'm doing that unless I come up with a circuit board adapter. it takes a lot longer than it looks!
