headphone amp question


I have an Antique Sound Labs MG Head OTL Mark II headphone amp and Sennheiser 580 headphones in my main system. It seems that the volume in my library (another room) is too much for my wife so I am looking to add another headphone amplifier to that room. Should I buy another ASL headphone amp or upgrade to the next level? I plan on keeping the Senns. I like them alot. What other candidates should I consider? I know there is another headphone only site, but I have grown accustomed and comfortable with the advice from Audiogon. Thanks for your guidance. And, by the way, thanks for years of advice and entertainment from this website.

Imo, upgrading is a logical step. There are good amps for the Sennhs on the market. How much are you willing to spend?
There's a Headroom Max unit available here today that would be hard to beat, even at $700. And NO, I'm not the
seller.
Not sure exactly what the issue is, but if the problem is sound leakage from the Senns, you might consider closed back phones.
I would recommend a Woo 2 or a Decware CSP-2 as an upgrade, or a Schit Valhalla if you want something cheap. Both will make Sennheisers sing. I would avoid solid state.

I don't know much about the ASL headphone amps...but they never gathered much of a following on Head-fi, a sign that you can do better for the same or less money.
You can take a look at the HA-160 or the 160D (with dac and preamp) both have nice synergy with sennheisers.

Maybe you can explain a bit more about your problem.
