New Tortuga passive/active tube pre looks like a winner
https://www.audiocircle.com/index.php?topic=163967.msg1767308#msg1767308 Initial comments from customers have been positive. Here's a recent customer post on our audiocircle.com forum. I've copied the text below.  Just got mine today at last. It ... 
Tortuga Preamps
Regarding "active forced matching" mentioned above, the way it's described in this thread is NOT how Tortuga Audio implements this feature. During normal operation of the passive LDR preamp there's zero active matching going on. That measurement c... 
New Tortuga passive/active tube pre looks like a winner
Hi All, Thought I'd pipe in here with some perspective. The LDR3000T is indeed NOT a passive preamp although it does employ our V25 LDR preamp controller/attenuator which is the heart of our current line of passive preamps. Downstream there's a ... 
Tortuga Preamps

Solid State Power Amps That Sound Most Like Tubes?
I just picked up a vintage McIntosh 4100 integrated amp at an estate sale. The tubiest SS amp I've heard to date. I've dubbed this amp "The Vinylizer" because it makes all my digital content sound like it's coming off of vinyl. I've seen these on ... 
Computer output to DAC, which route?
I have a custom desktop PC with a very good motherboard. I've been using the motherboard COAX into a Channel Islands DAC (VDA-2) for some time now. BUT!! Recently I purchased a $20 (yes, a mere $20!!) USB to SPDIF to compare performance. Wow was I...
