Just using contact cleaner to the whole volume pot (note: volume pot that I mean is the cylinder exactly behind volume knob)

I decided not to wait any longer and ordered a Soloist. Hopefully by the middle of next week I’ll be able to compare the LCD3, Magnum v4 and HD800 on the Amphora, Lyr and Soloist.

 

fun times!

 

(the Magnum v4 is going nowhere but I’ll be making a decision between the HD800 and LCD3 and between the soloist and the other two amps. Hopefully then I’ll be done with comparisons for a long while)

post #94 of 1185

Which headphone are you leaning towards keeping? 

post #95 of 1185

I’m hoping the HD800 are better in this setup (I owned the before and really liked them but sold them to try out high end stax) since I know they are more comfortable than the LCD3 on my head. So that would be a plus.

 

But I think I’ve been so smitten by the LCD3 sound that the HD800 may not hold up side by side anymore for my taste. I usually make decisions quickly - within a week - so I’ll know relatively soon which one I’ll keep.

 

A big reason why I wanted the soloist was because I’m still not 100% sure the Amphora is driving the LCD3 to their potential. Even though I really like their sound from the Amphora.

 

edit: I should have mentioned in my other post that I don’t yet have the HD800 in house. they should be here by Monday or Tuesday, though

post #96 of 1185

I found the Lyr a decent match for the HD800 but only with Amperex Bugle Boys in place. The synergy fell apart when those tubes started to wane and I was forced to use other types (namely Lorenz Stuttgarts, Amperex Orange Globes and others).

 

Impressions of the Soloist seems to point to a good balance with the HD800. It'll be interesting to read how it compares to the Mjolnir when that amp is finally shipped. Tempted to pull the trigger on the Soloist to do that comparison.

No question, not even remotely powerful enough to meet the 'recommended" minimum power spec in the manual ;)

 

The newer, balanced version is though.

Wait, there's a minimum recommended power spec for the LCD3? I don't have a manual, just the FR chart. (refurbed model). Do you mind saying what that number is?

 

All I know is that that the LCD3 impedance and sensitivity is not that bad. 93 dB and ~50 ohm. On paper (I know, I know), it shouldn't need a lot more power than some relatively efficient dynamics. To match volume, it requires about the same level on the amphora attenuator as the old HP1000 and PS1000 that I had and that's only around 3 clicks more than the Magnum v4 and MS2 I have in the house now.

 

Just for fun, I tried driving the LCD3 off the pico amp I recently purchased and that's a case where lack of power is evident. the amphora drives it a lot better (less shrill highs and deeper bass at decent volume) than the little pico.

 

Regardless, I'm looking forward to see what the soloist, with so much power on reserve, can offer (same deal with the lyr which is on its way, although I have higher expectations for the soloist)

It was part jest but Audeze suggests an amp rated to 2W or greater.  I believe the Amphora amp is rated at like 80mW.

post #100 of 1185

thanks for that. Soloist won't quite be 2W at 50 ohm but it should still pack a punch.

 

I had been looking for ages for some power specs for the amphora (or any RWA stuff outside their 5W into 32ohm for their balanced amp stage) and found nothing. You don't happen to remember where you heard 80 mW, do you?

post #101 of 1185

Calculator told me ;)  the RWA single ended amp is unity gain.  Take your source output and assume its below ~4V that's your ceiling.  Glorified portable amp really.

post #102 of 1185

Sorry, I'm not sure what you mean by unity gain?

 

I know it's a portable amp in regards to power but compared to the pico - which has 8V peak to peak - the Amphora delivers a better sound with more ease (both working on hi gain). It certainly performs better than any portable amp I've used so I had thought there would be more than 80 mW at ~50 ohm.

 

oh well. let's see how it fares against much more powerful competition.

post #103 of 1185

8vP-P is just shy of 3vRMS.  Neither are power houses, but they are battery powered so it shouldn't come as a surprise. Compared to the 10mW iDevices they are beasts though ;)

post #104 of 1185

oh yeah, they're absolutely more powerful than the iPhone. But I've owned more powerful amps in the past and, so far, the Amphora is keeping pace.

 

Oh, and regarding the soloist, Parts connexion has a special. 20% off and free shipping (canada post expedited for me). I didn't get confirmation of the price till I got the order pdf and a phone call this morning. (it still shows 999 on the website even after hitting checkout). They only advertise it as a cable special (http://www.partsconnexion.com/t/econnexion/0612/burson_promo.html) but you can ditch the cables and get 200 bucks off!

 

if you're on the fence, Solude, this may tip you over to order soon. :P

post #105 of 1185

And here I thought my days of having several amps at once were done /facepalm  Shot them an email.  At that price, its risk free essentially.
