Pass Labs:What to expect fm XA60.5 to XA100.5


Hi Guys,

Some of you may know that I have some buzz/hum issue in one of newly received XA60.5 mono blocks. The dealer diagnosed the problem and determined the transformer needs replacing. Since the XA60.5 is only few days old so I am given the chance to get a replacement set or I could top up the price difference to get the X350.5 or XA100.5s when my dealer gets their stocks in the next 3-4 weeks time.

Kudos to Pass Labs and the dealer's service for all the patience and after sales services...certainly very much appreciated and glad I go for Pass Labs.

As such, I have 3-4 weeks to listen to the current XA60.5 in my system while waiting for the stocks to arrive and make the final decision on the swap/upgrade.

Hi Peter,

Thanks for checking back.

Can you believe I am still waiting for the stock of Pass labs amps to arrive my local distributor. It's been close to 3 months in about a weeks time.
Would love to give you some views of the jump from the xa60.5 to xa100.5 which I intends to do.

Still waiting anxiously.... The dealer says the shipment is on the water and I got that since 1 month ago and still avail.

Will definitely update my views of the sound when I have the xa100.5 settled my small audio room.

Cheers
Hey Guys,

Just an update, finally my long wait for the XA100.5 ends 2 days ago.

Have it delivered, setup and running in my room.
Played for first 3 hours and already noticed the benefits of having more headroom even if its not required.

Cannot wait to run them in another 100hrs before giving further views against what i had previously experienced with the XA60.5.

Cheers
I am curious as to which amp you chose. Assuming that your speakers have a 90dB efficiency rating. You would only need about 1 Watt/channel to drive them to around 80dB at 3 meters so the XA60.5 should provide all the power that you need. See the following link for power calculations:
(www.myhometheater.homestead.com/splcalculator.html)

The advantage to Class A is that there is no distortion due to cross over from A to AB operation so operating at low power output levels won't be an issue. A couple of advantages that the XA60.5 has over the XA100.5 is the 33% lower up front cost and the 33% lower power consumption (200W versus 300W).
