Above posts about Pi4 are good info for a Pi illiterate like me. Since the Unison USB on my Iggy is taken, what would I need to add to the Pi4 to connect it to the coax or AES/EBU input? Thanks in advance.

I had no problem with ultraRendu into the Bifrost 2. What are you using to control the microRendu?

Thanks Jason. Outstanding customer service!!!

Hi all, have had my Bifrost 2 for one week now. Driven by an ultraRendu/LPS 1.2 it sounds fantastic. A definite improvement over the Bifrost MB Gen 5 it replaced. I'm hearing tighter/better defined bass and a soundstage much wider than before. Except for one issue I'm happy. The issue is...

Hi, wondering if you ever looked inside your Gumby to see if there was any evidence of a version 2......

Getting a good price on a used unit is hard to do. They all seem to sell for 85-90% of a new unit. That differential is not enough for me personally. Especially when you don't get a warranty with the used unit.

So I clicked on the thread to read your impresions. Where are they? Never mind, found your comments. Thanks.

I'd like to get in the Q for a Black/Black/Black unit. Two questions: My preamp has 13k input impedence. Will it drive that load OK? What is the capacitance on the MM input?

Greetings... Here's a pic of my SEX amp mounted on a custom chassis with a Foreplay III preamp. The SEX is used to drive my Audio Technica AHT-W1000s and AKG K271s. Both of which I learned about by lurking around at Head-Fi. (Thanks guys...) Mods to the amp include Goldpoint stepped...

My W1000s powered by a Bottlehead S.E.X. amp took about 100 hours to settle down. They blow away my AKG K271 Studios.

Supplementing my post above, here's an additional thought: With the understanding that the HD580 was born BEFORE the HD600 and HD650, the part was assigned its unique part number as "hd580". Then new products are developed. In this case, the HD600 and HD650. These products have some new...

Components of a particular product need to be uniquely identified so they can be "issued" to the assembly department when production planners decide to build a product. This is usually done in lot sizes that give maximum production efficiency. Each product such as HD580, HD600, HD650 will have a...

Thanks for the reply and for the Woo Audio 3 suggestion. Looks nice. One concern I have is that it uses 6DJ8s. Good ones are getting harder to find and expensive. Although my CDP uses them and I keep spares on hand, I would rather not invest in more equipment that needs the 6DJ8. With that said...

Hi, My first post here at Head-Fi... I have $400 to spend and a preference for tubes. I am looking at the Bottlehead S.E.X. amp or the Antique Sound Lab MG Head DT/OTL Mk III amp to power my AKG K271 Studio headphones. Any compatibility issues? Source is a Heart Audio CD6000ose. This is...
