LISA III Available for Order - Page 42

post #616 of 1070
lisa III is coming out soon and don't know if i should get the LLP or not... tempting...
post #617 of 1070
I am about to place my order for the Lisa III, I was wondering do you think I should go for the XP version or just the normal one?

Depends, definitely worth it if you can take the extra height of the amp I would think.

well, i found out i can use the
llp for 110 and 220 so
might as well go ahead and get it...

Is LLP available now? I have pm Brad but no reply.
post #621 of 1070
Haha, I had put my bets on today!

So Lisa standard uses two 9 volt batteries and can run 7 hours from 160mA's? That is a long run time from such a small amount of current. I guess it is using them in parallel and requires 18 volts.

Are there any more comparisons to other amps?

edit: I meant series, not parallel as parallel would double the mA's but of course only put out 9 volts.

Sorry to ask this question guys,
what's the differences between Standard version and XP version, beside longer battery life?

I actually only runs around 5 hours because of them having to use the same bias ratio for each when production began. Maybe this was changed for the new runs. These are also 150mah batteries. I kind of want to know if it would charge the batteries alright if I switch them with 230Mah.

Only that its 3/4 of an inch taller to fit all of those AA batteries.

The Expedition PIG POPPA Reviewed was an Expedition and was at a Higher Bias. Both these were prototypes. The CRD Diodes required for the High Bias setting became unavailable at the time the Mass order of parts for this Lot of Amps were ordered. One of the reasons Triad Audio is able to offer this complex of an amp packaged so well at this price point is not only the result of Design efficiency but in addition is also made possible by buying in Bulk.

All LISA III's produced for this first batch that are offered for sale at this moment in time are of standard Bias regardless of the model, both the Expedition and the standard models offered for sale are of the same Bias. The only difference Electrically between the two is the Up-graded batteries from 9 Volt 150 mAH NI-MH to 2000 mAH AA celled Battery pack and thus offering long run time between charges, Moreover since the Batteries are discharging at a small rate there life expectancy should be a Very Very long time. To acomidate this extra large battery the charging circuit is also reset to charge at a Higher current, this is simply done by changing a resistor and thus both Models use the same Charging Circuit except the current set resistor value is different.

I apologize for not mentioning this right away prior to your ordering, With all the many things i have had to do latly this detail sliped my mind.
Just so that everyone knows. If they reinstated the higher bias, I WANT.

Who has compared the normal and high bias versions and how much if any, improvement was there?

So the Expedition should run around 60 hours on the AA's. I wonder if they are going to use eneloop? At 2000mA's plus, there would be a nice run time as most rechargeables are about that mA rating now and there would be a very long period that the batteries would hold a charge with the added benefit that eneloops have a very low internal resistance that enhances current delivery, which translates into better sound. Although it could be that buying in quantity has already been done and 2000's were a good buy.

nay, it is in series.

AD744 does not like low voltages. They're some greedy little monsters. Parallel will only give you +/- 4.5V. Which is barely the minimum requirements of the chip.

I'm curious to know how the Lisa III holds up.
It sounds great, if talking to compare with other top of line portable amplifiers, it sounds the best significantly. In fact, it sounds closely to the high quality desktop head amp if matching a pair of good headphones. In my rig, it sounds particularly excellent when pairing with HD650 - one of the best synergy combinations for HD650.

As I know, in standard model the high bias is only available in those so called "Limited Edition" of first lot. I am glad to have one.

Oh I have the Limited Edition too! #5. yay.

I do really like it with the HD650 also.
