We have already been making custom headphone amp for HE6 based on the NSL. Since it demands 5watt into 50 ohms, it require a slight higher rail voltage than the NSL can put out. The NSL itself can drive be used as a 28 watt into 8 ohms amplifier to drive any headphone without adapter. But that shou...

NSL Headphone amp?

Have you given any thought to this, Gilbert? Could it be designed to meet the current needs of many of the flagship cans and wide variations in impedances for ore traditional cans, such as K7xx series and HD650?[/u]

Why not the BC 109? I'm sure Gilbert had a good reason.

We don't hear live music, or even the live studio version of live music. We hear recorded music: what's on the record, tape or disc, not the actual presentation. The mind has to do the transfer from the medium back to the stage. That's why we don't all agree, except when we hear crap recordings! I m...

Well, Gilbert...can you answer my question(s)? And can you tell me, if it will work OK with the SBH preamp you recently built for me that I added to the PS and cap pack? This preamp works very well with my 45 (tube) monos. It's pretty neutral and the bandwidth of the whole system is pretty wide, goo...

If you can, can you compare it to any transistor output stage amp (bi-polar, Jfet, Mosfet). Bob Neill, the Cr...

Re: HX

I wonder how long it will be before we're all converted back to solid state. We've become so used to the enriched sound of tubes, even just as inputs, that solid state, even extremely good solid state, initially sounds too cool and lean to us. But if the solid state really is good enough, we can ad...

My speakers are all easy to drive and/or sensitive. 25W is a lot of power compared to 1.5W
