It's the first time I hear (or read) about them...
I like the mute button, it's a nice touch.
Also I Wonder about the class A option and what difference it makes on the sound..

They need more info on the website that outlines the "Option". I found this through google searching.
Each channel may be equipped with a Class-A
Each output can be equipped with transformer
balanced outputs consisting of active feedback
Each channel may be equipped with a versatile
At that price, you would think someone knows the product.. No hit on youtube...

Found this list of recommended micpre's off the Royer FAQ sheet:
Do you have a list of recommended mic pres?
We've had the opportunity to work with many brands of preamplifiers and some stand out as real winners. In no particular order, here are a few we've had good results with:
Preamplifiers We Like
- Millennia Media HV-3 series (especially for classical work)
- Grace 101, 201
- Great River MV-2NP, MP-4
- Phoenix Audio DRS-2
- Sonosax SX-M2 (for portable or field work)
- John Hardy
- Universal Audio
- Rupert Neve Portico
- Summit Audio 2BA-221
- Trident Audio
- Daking Mic Pre/EQ 52270
- Gordon Instruments
- A Designs MP-2
- Pendulum Audio MDP-1
- Groove Tubes Vipre
They don't list Focusrite, I bet it's because of their transformers.. or they just didn't care for testing them (other pre in the list have transformers)
I use my ISAs with the 2 cascade Fat head I have.. Can't for other mics but with those, they work...
Many on the list are tube mics... makes me realise I never tested the fathead with my UA-LA-610s.... ;)
Hey wait, why haven't they put Universal audio in the tube lovers section ?

[/SPOILER]and love that but I'm thinking I would like to add a different design with a transformer now.
I owned the Great River MP-2NV and found it okay for guitars but didn't keep it. I may consider Hardy next.

To transformer or not to transformer?
Many modern solid-state preamplifiers have eliminated the traditional input-coupling transformer altogether, and in many cases the output coupling transformer as well. This not only saves space, weight and money, but also offers a more direct route for the signal to travel as it makes its way through the signal path.
So, do transformerless designs sound better? Not necessarily! Transformers add their own special alchemy to the mix. Call it coloration, but transformer coupled designs tend to sound punchy and full-bodied. Transformers also offer the benefit of true electronic isolation. This greatly enhances a preamp's ability to interface with other equipment with minimal noise, RF, hum or induced interference. Once again, it's a matter of taste and, in some cases, budget. Transformer coupled amplifiers usually cost more than their ironless cousins.
I love how that Lake People pre looks. (looks can be deceiving :cautious:) The tranny option for these looks interesting.
Gain structure looks smartly done.

you had very sexy units in your racks overtime Chris... I wish I could have tried all the stuff you used ;)
The Lake People unit looks good and has impressive specs. One practical thing would make me a little cautious: from my long design experience, it's not really possible to build a quality design that has optional components, particularly when it comes to transformers. You design as a whole, as each part influences everything else to a greater or lesser extent.

I know . I have great memories enjoying sitting around all that gear. But at least I can share my experiences with you :) In total honesty, I sold most of it once the CDN dropped below 80 because a DAW does it better. UA gear is special. So are Pultecs. The Pulse ones.
I still have LA2A's and 1176's.
SPL Premium mic pre's are really sweet. The m-2b I rave about all the time is stunning. Absolutely beautiful on piano, guitars, vocals. I hope to pass that onto my kids.

You are so sharp, Bos. I was thinking about that too. I mean, why wouldn't they make the best unit without compromising the integrity of another. I guess they are tweaked different.
