Has anybody heard the new Audio Research LS 27?
6550c, perhaps the point I was trying to make:) 
Lightspeed Attenuator - Best Preamp Ever?
No, it is not an IC issue. 
Lightspeed Attenuator - Best Preamp Ever?
I think the Audiopax is a fairly low gain amplifier (17db and less?)- it might need some additonal gain from an active preamp, or possibly a TVC passive with 6db gain. No expert on the combo you have, but a guess. 
difference between an active and a passive preamp?
A very good question, After having owned some of the finest tube line stages, and almost every type of passive, and given that I have low impedances sources with strong analog output, short, low capacitance IC from "pre to amp, and a sensitive (1v... 
Lightspeed Attenuator - Best Preamp Ever?
George, is it correct that as the volume is louder (less attenuation) the output impedance goes up? If so, given that I can switch my CD output from 2v to 4v, does it make sense to use the higher gain so I can use the volume control at lower setti... 
The best passive preamp
Interesting to hear Roger's changing view of resistors versus transformers, I wonder what is causing that, but alas, another thread....actually, probably relevant to the thread. TVC / Resistor and balance control are key choices for the best passi... 
The best passive preamp
Is there balance control with the MLA, or just tight mathcing between channels. I think we might be both of the mind that channel balancing is an important "preamp" function, but most passives don't seem geared up for that. 
Best tube pre-amps under $1,000
I would get a new Mapletree Audio linestage or full funtion preamp at this price point and even if I could afford considerably higher. Not audio jewelry (thick aluminium or steel face plates, etc) but well thouhght innards and curcuit design and t... 
Atma-sphere MA-1 mk 3 to 3.1 upgrade
Jtimothya, I did the amp upgrade. What do you know of the 3.0 - 3.1 upgrade for the preamps - same thing? As important an upgrade? My 3.0 is of fairly recent vintage. Already have the power supply and VCap upgrades. 
Lightspeed Attenuator - Best Preamp Ever?
George, roughly what is the tolerance for channel to channel matching, and do you feel that is stable for the useable life of the product? 
Has anybody heard the new Audio Research LS 27?
I agree with what you say, to me it is a bit of the hyped up nature of things in this hobby, you would think this stuff sounds more real than real by now:) I think most of us can also agree that ARC has been making wonder tube preamps for a long t... 
Has anybody heard the new Audio Research LS 27?
It does seem automotive technology has changed dramatically over the past 40 years, not so with linestage circuit designs. For those with money to spare, getting the lastest ARC then flipping it 3 years later for the latest ARC is fine -why not, d... 
Has anybody heard the new Audio Research LS 27?
I guess the question is whether in fact the many models and revisions of those products over the years were in fact the result of continuous improvement of preamplifier performance, or in fact the result of calculated product marketing strategies ... 
Shindo Cortese - First Impressions
Are these 10 watts somehow more capable of driving speakers than the power rating would suggest? or do you really need 93-94db+ sensitive speakers to consider it? 
Lightspeed Attenuator - Best Preamp Ever?
I agree Anthony, and really it comes from Roger's insistence that a passive preamp (with his amp) is the way to go, "no active will be better, but I will build you one if you insist" - he may have said "can be". Doubting Roger is not usually a goo...
