What drives your LS35A?

Postby mva » Wed May 18, 2005 2:57 am

The amplification which I currently use to drive my LS is an ST 70 which I picked up from Sir Rene Rivo.

I am not very knowledgeable when it comes to tubes but I believe the output tubes are EL 34 Mullards; whereas the other tubes are composed of a pair which has (USA 7199) written on it and a singular tube which I believe is a Sylvania. My apologies for my ignorance when it comes to tubes. However, I would like to clarify that ST sounds magical.

I hope Rene could help me further explain the tubes he used in building the ST that I am a proud owner of.

The two best sounding amps for LS3/5A in my limited experience are, Eico HF-60 (EL-34 PP 60w) and a pair of Leak TL12.1. (KT66 PP ?w).
Strangely a Sun Audio SET 2A3 actually sounded fairly clean at Ferdie's store Sounds N Images in Cebu. This was unexpected, just goes to show synergy is what it’s all about sometimes....Dan

I used to drive my LS 3/5a with a Luxman receiver, a 45 watter ss amp, and it sounded as good as tubes. The Cyrus mission amp I heard are equally agile performers on the LS. What I'm saying really is there are a plethora of amps that can work equally well with the LS 3/5a. It should widen your choices rather than sounding pathetic coz you can't buy it the so-called best amp. There's no doubt there's more probably on the tube side of audio that can weave magic like that old Luxman 3045 monos (if I got the model right) as I recall in the U.S. LS shootout that turned out more like which amp drove the LS better.


I am now driving earful's LS3/5A clones (Ho's) with the Flying Mole SS monoblocks. At 100 watts per side, it has all the power it needs. The Moles also have the warm sound of tubes and does bass like no tube amp I've heard.

Based on what I've heard, the real mate for a pair of Moles monoblocks is the Tono preamp! Moles have pretty much driven any speakers I've tried with it, including boombastig's power-hungry 4-ohm Genesis IM-8300 with ribbon transducers.

I agree on the synergy of DAD100 amps with Tono preamp especially with cleartops on it.
Digital amps seems to sound better with some tubes anywhere in the system

Boss Bunnie, you forgot to mention your amplification yata. We know you have three (?) pairs of speakers rotating duty depending on your mood. What amps rotate driving duties? The curious want to know. :)

i brought out the LS3/5A this evening. they are blu-tacked on a DIY 29" stands (made of solid ipil wood). hooked them to a pair of restored Eico HF35 monblocks (35wpc). front-end is the newly modded consonance 2.3 into the restored/upgraded modulus. this system creates such a huge sound one could scratch his head in bewilderment where all that big sound is coming from :-)

of course, from a pair of little giants! :-D

I will suggest it again, drive the PWM with a low impedance(700 or below) tube based active preamp and you will never go back to conventional stuff. :)

Here's something I read in the Harbeth forum
----
Message #5 of 7: Date Posted: 31 Jul 2005 10:24:08 by Paul G Smith
The LS5/8 was originally (and often still is) driven by a modified Quad 405or 405-2 with an electronic crossover, one channel for the woofer and the other for the tweeter, then latterly by a Chord power amp. The other non-active monitors are driven by various power amps. Typically the S3/5 on OBs was driven by an H&H 30W monoblock, the AM8/12 in BBC parlance, but in studio situations Quad amps such as the 306 are frequently found. We now use a small amplifier by Canford, a studio supply company, to power our LS3/5s on OBs as they work and are small! I suspect we may start looking at Flying Mole amplifiers too.
Hope that helps


Paul

Hi Alan,
A question has been raised on the LS35/a forum about what amplifiers were/are typically used by the BBC with LS speakers. I wondered if your experience at the Beeb could help...
Thanks.

Hi Jack,
Medyo late ang sagot ko to your post sometime May. Anyway I use a Dynaco ST70 with Winged C EL34 and Mullard GZ34 tubes to drive the Rogers 15 ohm. I also use the 16 ohm speaker tap. I have also tried using the ARC VSi55 to drive them but it seems mas match ang LS35As to the ST70. No more experimenting..... ST70 permanent mate of LS35A.
The other speakers dont seem to have matching problems with either amp.

I am fortunate to have on a pahiram basis a Quad 22 with Quad 2 mono amps powered by GEC kt66. So far, this is the best preamp/amp combo for the Rogers LS3/5A 15 ohm I have tried. For those of you who have the LS3/5A, I suggest begging, borrowing or stealing the Quad combo.

youre comparing apples with oranges. the ja30 is of a different league over the quad2s.

There is just so much performance in the Rogers LS3/5A that we realize it's performance improves with every improvement in amplification used. This speaker is a true classic. The best sound I've heard was when a Forsell amp was used to drive a pair of 15 ohm LS3/5A.

I am driving my 11ohm non bi-wire Roger's with a vintage Fisher 500C through its 8ohm taps. It has H.H. SCOTT labeled 7591 tubes. Through the years I have driven these Roger's with Quad, McIntosh, C.J., ST 70, Sonic Frontiers, etc... So far this Fisher amp seems to be the most satisfying combo with the Roger's, specially when it comes to bass reproduction.

My 15 ohm Rogers have found their match! The Marantz 2330B! They are now making sweet music together!

Nait 5i can drive it easily, but its best w/ tubes like Dynaco ST70, Quad II tubes, etc... a bit tricky matching these speakers... not all tube amps sounds get w/ them either.
