EL84 amp Vs. EL34 amp


I currently own a very nice sounding 12 wpc Audio Space Mini Galaxy EL84 int amp. Its a 2 chassis piece with separate power supply and adj. negative feedback switch. I've been thinking of getting an EL34 int amp in the $4-500 range just because its more powerful and I would have more speaker choices.

I've read comparisons of EL34 and KT88 tubes, but sonically, how would you compare EL84 amps and EL34 amps? Is the EL34 just a more powerful version of the EL84?

I look forward to your responses.

Thank you all for your posts. Please keep them coming :)

Its been about 15 years since I owned any EL34 amps (a cj MV50, Music Reference RM9 & AMC CVT3030 int) and probably about 3-4 years since I actually heard an EL34 amp.

Unfortunately, the EL34 amps that I owned at that time were kept for only a few months as I was going thru a transitionary stage and evaluating a lot of different gear at the time.

Ever since I got rid of my Omega Grande 8's about 2 years ago and with this economy, I've been on a hunt for the best sounding speakers I can find for under $200 and have gone thru about a dozen pairs of speakers since then. The idea of getting an EL34 amp and more power is to widen the field of possible speaker choices. From the responses so far, perhaps the EL84 (6bq5) may better suit my tastes, although it limits speaker choices somewhat.

Lou, I have the RM9 Special Edition $9,500) and the RM10MKII ($1950) and can tell you that is 30 watts is enough power the RM10 is about as good as the come and you find them for $1,000 used - you also get 10,000 hours of tube life and they are relatively cheap tubes, and they only use for output tubes. I think both tubes are special, but the difference are what has been described. But you know Roger would never build a warm, euphonic amp!
The el84 and el34 are my two favorite sounding tubes.

What you really need to look at is how their characteristics are going to integrate with your speakers. The speakers are a much larger piece of the puzzle- feeding them properly is critical.

I would choose the speaker first and then consider how to drive it.

One other thing to note is that I don't think it is neccessary to spend the kind of money you are talking about. If you look at what goes into a push pull tube amp, even one that is point to point hand wired it just cant justify $5k in my opinion. These are simple circuits with relatively few critical parts. $.02
The RM10MKII is $1,950 spanking new and since they are incredibly reliable, they are an excellent used buy at $1,000 and with right speakers are as good as any amplifier out there, with the possible exception of OTLs, but that is another kettle of fish. Seriously if 35 watts enough power, you should consider the Music Reference RM10. Also works really well with a passive pre due to its hign input impedance and sensitivity, making for a low cost SOTA amplification system.
Thanks again all for writing in, but I think several of you are adding a zero to my budget. My amp budget is in the $4-500 range, not $4-5K range. Sorry, just can't afford the expensive gear these days, and in the process have found some really great low cost sleepers.
