modified jolida 100, mh cd-25, or audio aero prima

Milind, no one should give final judgement on the Jolida without upgrading tubes, and without breaking in. Your modified Jolida will come with Svetlana tubes. This will give you the impression the mod Jolida is better. Whereas, I can tell you the Svetlanas can be bettered still.

I can't say the Jolida has the last word on bass, compared with solid state. It is a true tube powered unit. Everyone knows tube bass sounds different than solid state.

I enjoy plenty of bass with my stock Jolida, and it is a musical bass.

A friend of mine and I switched out his Telefunken tubes in his Llano amp with black plate 5751 tubes. The black plates sounded more natural.

Hi Muralman1,

There is no doubt that this is musical CD player, The stock jolida is itself a very good player, I heard Aracm FMJ 23T, CD-72 with Bel Canto, Rega Jupiter and Planet, They have their own strength and weaknesses, Any day I will buy Stock jolda over these payers, just because how musical it is, the vocals and soundstage are like no other CD Player, In that area its in a different league, I know more than these mods, the tubes will make lot of difference and svetlanas can be bettered by other tubes, I believe in your judgement, your experience with all these tubes will help me in getting the better tubes, so whenever (even a month) anyone thinks its a right time to post impressions about the new tubes, it will help the newcomers like me, that's the only point.

Regards,

Milind

My vintage RCA 5751 black plates arrived yesterday I installed them ASAP, warmed it all up about 5 hours and had a listening session.

The BP5751's have more solid adn immediate bass, acceptable dynamics, they seem a little more reserved in the mids, but still quite nice. These are the most expensive Tubes I have, but....

I think I still prefer the incredible 3d soundstage the EH 12ax7eh's are throwing, even if I have to live without the SS like bass the 5751s give.

I have ordered a pair of EI ECC83 low noise 12ax7's, they should be in next week. I'll give an impression of them as well.

I am going to leave in the RCA 5751's for a while however, as they are pretty darn good.

Distortion, you are just reminding me that we all will hear different responses depending on strengths and weaknesses of team components, primarily speakers. Some speakers are noticeably bass heavy. Others might have a bright tweeter. My speakers are fairly civil, and sound best with a neutral tube.

When the Telefunkens were exchanged for my Sylvania 5751 tubes in the Llano, the transformation left all listeners speechless. That was with using Martin Logans.

The bass was tight, and musical, the mids clean, the highs sweet and fully articulate. Images were natural.

I enjoy the same response with my Jolida/Pass Labs/Apogee combo.

Since 5751 tubes are getting hard to impossible to find, and with the prices soaring, it would be great, if in your tube rolling, you find a good substitute.

Just for the experience maybe you should plug in some of the tubes I seem to be drawn to. You couldnt be more right about the system components and the tubes synergy.

Here is a link to a spot were you can buy them The Tube Store.

They(EH 12ax7eh's)are only $9.95 each, so what the hay.

The RCA 5751s are gonna stay in for while and then I will swap back. Sometimes I feel like I get acclimated to a certain sound and any change is perceived as bad.
