Just got the notification that the eagle lands on Thursday. And since Friday is the first day of my very last vacation, the timing couldn't be better.

On the Audio-Scape website, he criticizes another manufacturer doing a 2U version of the LA-2A, saying corners are being cut. Could it be Stam ? I'm asking out of curiosity, not to bash one or another, I have a Stam SA-2A that I love btw. Just technical curiosity (walking on eggs, here...) Warm is also 2U. Makes more sense.

He does make some more specific criticisms: "Some of these clones have things that shouldn't be there, opamps in the metering section, non original power supply scheme and modify tubes in the side chain..." I don't know enough about the guts in these units to know whose clones he's talking about.

I was very disappointed by the UA LA2as and 3as compared to the real UREI ones from the late '60s. Clones ought to sound lots less colored!

Both have non original power supplies. I do not know how much difference this makes electrically.

Warm is good... not great to me... still I love hardware over plugs and use it for tracking mostly.

I can't say very disappointed. The build is nice and solid. But I was underwhelmed until I replaced the tubes and opto attenuator. I may have gotten a bad batch but it really made a difference , to my ears anyway.

I was comparing the first batch back in the '90s with UREIs from the '70s.

I opened mine up today after I wrote the post earlier. They really did do a nice job. Also shows what a fairly easy DIY this would be! Attachment Deleted

In that case here is a pic of the back so you can see the I/O transformers , opto cell , tubes , power trafo etc. Looks like all the AudioScape workings is inside on the PCB. Attachment Deleted

The Stam sounds really good. Only issue is if you can wait for it.

This is the inside of the Audio-Scape Opto. I don't know much about electronics so I'm not sure if I'm justified in feeling underwhelmed when I compare this to the pictures posted of the real LA-2A guts. Perhaps some of you more knowledgeable gents can weigh in on that topic. I'll rack it tomorrow and test it out this over the next week.

Not directly LA2 related , but UA lost me for analog when they revised the 1176 sans attenuator without telling anybody!

Some people swear by point to point, others extol the consistency of a well laid out pcb. Given the price point, I don’t see anything surprising or disappointing here.

I like my Warm WA2A a lot but I don't have a real LA2A to compare. I think it compares very well to the ADL 1000 or plugins. In youtube comparisons with the Stam I thought the Stam sounded brighter but not necessarily better. Just different. I am very curious about the Audio Scape LA2A though.

There is a rea I stand corrected. I wasn't meaning to paint your gear in a negative light at all. In fact I would have brought your products if they had been around when i was DIYing all of my studio equipment. Much less hassle and great value for money. You were just about 5 years too late for me to jump on the band wagon.
