Any reason to go with anything other than Sanders Magtech for Martin Logan Summit X
It seems like the Pass X series amps have been a popular option. I've been using an X350 on a pair of Ascent I hybrids for years. Sounds good and really reliable. I'm more worried about the panels than the amp. I use an ARC Ref 5 for a preamp. 
ARC Ref 75 SE issues?
Does ARC have service centers and dealers to help with these repairs and questions? The factory service has been getting harder to deal with the last couple of years. Local service centers would take a lot of anxiety out of purchasing new and used... 
Looking for great Amp for Martin Logan Prodigy woofers
Two VT100s would generate a lot of heat. Not saying it's a bad idea, I've had one and replaced it with a Ref 110. People do bigger tube amps all the time but that's like 7 or 8 amps of standing current and 16 6550s in one room.That's dedication. 
Recommendations of amp for Martin Logan Summit X
Used Pass X series? I use an X350 on a pair of Ascents.Good hunting. 
Are sound bars worth it?
So the LG I got earlier this year has ARC (Audio Return Channel) on one of the HDMI connections. I'm using that to feed a Yamaha sound bar (YAS-107). The TV automatically turns the bar on and off and controls the sound bar volume.While I'd never m... 
Upgrading Tube Preamp from Audio Research LS-7 - Recommendations for better soundstage?
LS 25 or 26? Similar ARC house sound with a single gain stage and cathode follower with no feedback. The 25 mk2 and 26 are especially quiet but if you have a stash of 6922s then a 25 Mk1 is an option. The 26 has good stage width. Also really nice ... 
Looking for great Amp for Martin Logan Prodigy woofers
I did a passive biamp using two Adcom GFA5802s on my Ascent i hybrids and I was happy for several years. When it came time to upgrade the amps I went to a single Pass X350 and still haven't looked back.I guess my point is that one really good amp ... 
Are Pass Labs amps good at low volume levels?
X350 > Martin Logan Ascent i and F5 > Altec Model 19 owner.I think his high bias / class A designs sort of idle in the sweet spot so they work very well at low levels and are very capable with quieter music.And he owns First Watt so obviousl... 
General question about tube preamps and gain
I don't see why not. Realistically a lot of preamps and power amps have more gain then they will need. So the preamp many times is running at the bottom of its dynamic range. 
Just auditioned Martin Logan ESL vs 60xt
A lot of it might have to do with setup. The panels radiate front and back. They rely heavily on ambience from the area behind the speaker and proper spacing. They're also very directional despite the curved panel. If they sound dull that might be... 
A civil discussion about the state of Audio Research
Things have changed there.My Ref5 has been at Service Repair for about 5 weeks. I actually received a notice on 9-17 that the repairs were completed and that I would receive a statement and the unit would then ship. I never received the statement ... 
Tube amp forethought
Check out the Audio Research Documents page. They have biasing instructions for most all their classic amps. Usually, although there are exceptions, all you need is a small insulated screwdriver, a meter that can read millivolts and the restraint ... 
How could 100 Watt class a has more head room than a 300 Watt amp Class AB
From what I've seen in the Stereophile reviews the Pass XA series amps are rated for their class A power and not peak power capabilities. It looks like they tend to double when run up to the limits of the power supply.From the Stereophile XA60 rev... 
Pass amp paired with audio research pre?
Sorry I'm late.The Ref5 has two parallel outputs. One connects directly to the X350 which drives a pair of Martin Logan Ascent ES hybrids. The second output goes to a dbx 223XL which drives a single SVS PC Ultra. The 223 is just used as a low pass... 
ADCOM
In the past I've used a GFA5802 to drive Martin Logan Ascent ES hybrids. All MosFet heavy bias AB amp. A fair amount of heat but no fans. I had to go to a Pass X350 to upgrade. The Adcom is still on active duty driving a pair of JBL 4430s.It's a p...
