The Isabellina HPA will be fine driving headphones down as low as the 16 ohm range.

The Amphora can do this as well...

Yes - at the meet in Denver last weekend the 9v Amphora had no trouble driving a modded Denon D2000 and modded D7000 at the same time, with no audible effect on the sound when plugging in and removing one of the two 25 ohm headphones.

Also, the Amphora is the best amp I have here for driving the 16 ohm Sennheiser IE8 to sound their best, without bloated bass or sucked out mids.

All,

More Isabellina HPAs shipped out today, and I'll be shipping a few more tomorrow. So I expect that just about everyone (except for one or two who ordered late) will receive their units by next week!

Yes - I'm really looking forward to your impressions. I'll ask Ken about starting a new thread on his forum for Isabellina HPA impressions.

I already received a quick email from a customer who received his HPA this morning:

As always, your feedback and support is very much appreciated!

New Isabellina HPA build schedule

All,

I forgot to mention:

I have parts on order for a second production batch of Isabellina HPAs. I should have all the parts around mid-August, and then will begin the second batch. I'll keep everyone updated just like for the first batch.

I already have received some emails from those who want to order for the second batch. Just like for the first batch, please email me and I'll add your name to the list. When I'm ready to begin production, I'll contact you requesting payment, and will build in order...

Ken at ALO already is on the order list for this second batch and will be selling them on his website as well.

The Isabellina HPA is a 'smokin good' dac/amp combo and I know you guys are going to love them!

Best regards,

Vinnie

Well my Isabellina HPA arrived today! Very fast shipping, thanks. The unit was very well packed and it comes with a nice set of instructions as well as an USB interconnect.

The unit is currently burning in, I am using an older Philips DVD Player via coaxial and it is driving a MarkL Modded Denon D5000 w/ Bubinga Wood cups. Straight out of the box w/ no burn in I found the sound a bit muddy and lacking definition/clarity. Bass is deep although a bit out of focus, treble is not very extended. Not worried since a lot of gear starts life sounding not very good only to blossom w/ burn-in. Vinnie recommends about 200 hours which may take about a week depending on how long the sealed battery lasts and how long it takes to charge (expecting a +/-2 hours charging time).

Anyways I took a few pictures for your viewing pleasure.

Very Nice Miguel! Congrats. Looks very nice. I'm sure it will open up a lot after break-in.

Congratulations!
The Isabellina HPA sure looks really nice, and I am sure the sound will tighten up after the initial burn-in as well.

Just been notified that my Isabellina HPA is already waiting for me at home. This surely makes my working day today extraordinary long.
