Thanks Murphy.   Which Passlabs model do you have?  Any tips to make it sound better?

Trying to emulate the familiar look & sound of the legendary Mcintosh Amps?

The looks maybe but I don't think Passlabs current point 8 series sound anything like Mcintosh.

Looks Mcintosh may win hands down but in terms of sound, anybody ever compared with similar amps from both?

Bro Francis, for you price no object, it's ok, but for those price conscious, like most of us here, what is the price to performance between these 2 brands? That's to say to achieve the same performance, how much are the price point for their respective amps or simply put, which is cheaper? That's what I'll need to consider first.

Personally, I prefer the looks of the Mcintosh but performance will still be priority but then if factoring price into the equation, then will have to see how much will be the impact in terms of cost to performance ratio.

Thanks Murphy.   Which Passlabs model do you have?  Any tips to make it sound better?   

I had various pre and power models. The last I used was a Pass X350.5. I had the Xp20 which was swapped to a audio ref ref 5se. Pass was under symposium platforms and footers. Pass amps need to left on for at least 2 hours before they start singing. I used to.leave it on 24/7 could not take heat and electricity bill.

Well, I have to say it is not fully run-in yet as it was delivered last Thursday by High End Research.  It has just gone pass the 30hrs mark and as it is, the sound is very smooth, similar to a tube amp and with very good resolution.  The bass control is superb and I am hearing plenty details.  It is very musical also and this is especially important to me as I am so used to the sound of tube pre and power amps for so many years.  For me, it is a very worthwhile upgrade.

Did you compare the X 0.8 models to the one you bought? Just wondering what the difference in sound is like.

I have a X350.8 which was recommended by Pass for my speakers which have a low impedance dip.

Murphy, thanks for your input.  I will be trying out some footers under the amp but the amp runs hot and the limited space above the rack does not help with tall footers such as Cerabase Compact.    Agree that it does improve significantly after the 2nd hour.  I have to put it in on standby mode when not using to reduce the startup time.

No I have not tried as most of the folks I know are using the XA series which is Pure Class A compared to X series which is AB.    What speakers are you using?

I would.suggest you consider the gyrotension  Vega as well. I think they are very good.

You may wish to contact Colin or Philip from HER and ask them for advice whether changing to the XA.8 series makes a significant improvement compared to your X350.8 driving your current speakers.
